There is no beach-day hero quite like a crochet sarong. One breezy rectangle of cotton lace can take you from the water to a seaside lunch without a single outfit change, and because you make it yourself, it fits exactly the way you want it to. So I have gathered twenty of my favourite crochet sarong ideas for you, all genuinely free, from true tie-on wraps to triangle shawls that double as sarongs and a few clever beach skirts that do the same job with a little more structure.
A quick honest note before we dive in: the first dozen or so are true wraps and sarongs that tie around the waist, and after those I have included convertible wraps and pull-on beach skirts that work beautifully as sarong-style cover-ups — each one flagged in its description so you always know what you are making. Every pattern below is free in the form I describe, whether that means full text on the designer's blog, a free download, or a free video tutorial, all in breathable cotton or cotton-blend yarn.
1. An Asymmetrical Lace Triangle That Wraps Three Ways
We are starting with the prettiest kind of multitasker: Brianna Iaropoli's lace sarong from Life and Yarn, an asymmetrical triangle that starts at one corner and grows outward with an increase every few rows, giving it a lovely stepped edge. The longest side measures a generous 80 inches, so it wraps comfortably around a wide range of hip measurements, and the gauge is 17 stitches by 8 rows in half double crochet per 4-inch square on a G/6 4 mm hook in DK or worsted weight yarn. What I love most is the versatility the designer builds in — this same piece works as a sarong over your swimsuit, as a striking shawl over your shoulders, or even as a scarf on a breezy evening. The full pattern is free on the Life and Yarn blog, and although it looks intricate, it settles into a simple repeat after a few rows. Make it in a soft sea-glass blue and it will go with every swimsuit you own.

2. Sideways Shells With Ties You Sew On Yourself
Chez Pascale Designs gives us a sarong with a construction twist I really appreciate: the Hanging Shells beach sarong is crocheted sideways in a simple two-row shell repeat, so you choose one of five length options before you even begin. The side ties are made separately — chains of 100 with single crochet rows worked back along them — and then sewn to the sarong's corners, so they sit exactly where you want them and feel secure when knotted. Because the stitch pattern is so straightforward, this is a wonderfully relaxing make, the kind you can work on a porch with a cold drink nearby. The complete pattern is free on the designer's blog, and the shell texture catches the light beautifully in a crisp white or sandy natural cotton. If you have ever wanted a sarong that looks boutique-bought but cost you an evening's crocheting, this is the one.

3. A Fringed Triangle in Four Skeins of Cotton
Sarah Liz at Crafts by Sarah Liz made her beach sarong the way so many of us actually crochet in summer: quickly, simply, and with fringe for fun. The piece is constructed like a triangle shawl, starting from a magic ring and growing outward with double crochet and chain-space mesh, and it finishes with a playful fringe along the edge. You will need four skeins of Lion Brand 24/7 Cotton and a K 6.5 mm hook, plus scissors and a needle for weaving in ends, and the whole pattern is free on her blog with the instructions written out row by row. Using only chain, single crochet, double crochet and increases, it is genuinely beginner-friendly, and the cotton survives sand, salt water and repeated washing. I picture this one in a bright coral or turquoise, worn knotted at one hip over a plain black swimsuit.

4. A Tutti Frutti Triangle in Self-Striping Yarn
Jennifer at Fiber Flux has a gift for beach patterns that look far fancier than their stitch count, and the Tutti Frutti beach wrap is a perfect example. It is a triangle worked in friendly V-stitch rows, and the magic comes from self-striping yarn doing all the colour work for you — no ends to weave in every two rows, just one happy rainbow unfolding as you crochet. The finished wrap measures about 42 inches across the top with 34-inch sides and 18-inch ties, sized to wind around the waist and knot over a swimsuit, and the full pattern is free on her blog with a video tutorial to walk you through it. The designer styles hers wrapped around the waist over a swimsuit, exactly as I would. Choose a fruity stripe and let the yarn be the whole outfit's talking point.

5. A Granny Stripe Wrap You Can Wear Four Ways
Our second Fiber Flux wrap is a different animal altogether: the Beach Cabana Cover Up Wrap is a granny stripe triangle, worked in cheerful cotton stripes, with long ties made by chaining 65 and working double crochet back down the chain. The designer's styling notes are what sold me — you can wear it around your waist as a sarong, over your shoulders as a shawl, slung over one shoulder for a completely different look, or even as a scarf when the evening cools down. The pattern itself is free on the Fiber Flux blog, with a video tutorial included, although a paid PDF of the same design is also listed on Ravelry, so make sure you follow the blog version for the free one. Granny stripes work up faster than you might expect, and in bright beach-towel colours this wrap is pure holiday energy. It is the piece I would pack first for a resort trip.

6. A Beginner Cotton Sarong You Can Finish in a Weekend
Christina Landrum's Cotton Beach Sarong is the pattern I recommend to any friend who says she has never made a wearable before. It is rated beginner, takes just one ball of cotton yarn and an H 5 mm hook, and comes together in about two to three hours — genuinely a single-weekend project. The finished measurements are a neat 39 inches by 17 inches across the top and 35 inches by 17 inches at the bottom, a tidy wrap shape that ties comfortably over a swimsuit without yards of excess fabric. It is a free Ravelry download, and the simple single and double crochet stitch pattern lets a pretty cotton colour shine. In a soft sage or dusty rose this is the understated sarong you will reach for every single beach day.

7. A Sparkly Trimmed Mini for Evening Beach Walks
Aprile Mazey's Sparkly Trimmed Crochet Sarong is the after-dark member of this collection, and I mean that in the best way. Worked in two colours of number 10 crochet thread on an E 3.5 mm hook, it measures 50 inches wide including the ties by 20 inches long, with a contrasting trim worked around the sides and bottom edge that gives it a delicate glint in low light. The stitch pattern is simple single and double crochet, so the sparkle comes from the thread choice rather than any tricky technique, and the gauge is 16 double crochet to 4 inches. It is a free Ravelry download for an adult or teen, and I picture it over a black swimsuit with sandals for a beachside dinner. If you have never crocheted with thread before, this small project is a lovely first taste.

8. A Traditional Wrap Skirt With Room to Size It Your Way
Elena Hunt's Amazing Grace Bathing Suit Wrap is a traditional wrap skirt in the truest sense: you wind it around yourself, tie it at the waist, and adjust it to fit your body rather than the other way round. The free pattern on the Beatrice Ryan Designs blog is written for an average women's large and includes instructions for making variations to fit many sizes, so you are not locked into one set of measurements. It uses light DK weight yarn with a K 10.5 6.5 mm hook, which keeps the fabric soft and drapey rather than stiff, and the wrap-and-tie wearing style means it flatters a wide range of figures. This is one of Elena's Amazing Grace series of patterns, a collection with a lovely pay-it-forward spirit behind it. In a classic white or navy it becomes the timeless cover-up you will still be wearing five summers from now.

9. Stacked Shells Inspired by a Caribbean Island
Diane Hunt designed the St. Croix Beach Wrap for Cre8tion Crochet with the colours of her home island in mind, and you can feel that inspiration in every row of stacked shell stitches. The wrap is worked in DK weight yarn on a J 6 mm hook, and the designer encourages you to make it any length and any colour you like, so it is easy to size it as a shorter sarong or a longer wrap. Here is the convertible part I promised to flag honestly: this piece can be worn as a stylish wrap for your top or as a skirt for your bikini bottom, which makes it two cover-ups in one project. The full pattern is free on the Cre8tion Crochet blog, and the shell stitch gives it a gentle, wave-like texture that looks wonderful in turquoise, seafoam or any ocean-inspired shade. Wear it as a skirt by day and throw it over your shoulders when the sun starts to set.

10. A Convertible Triangle the Designer Styles as a Sarong
Kaitlin Barthold's Seaside Shawl from Originally Lovely earns its place here on the designer's own framing: she describes this convertible triangle as a piece that can be worn as a sarong, a scarf, or even a top, and the sarong styling is genuinely convincing. It is rated Easy Plus and uses four skeins of Lion Brand 24/7 Cotton with an I-9 5.5 mm hook, so the fabric has that sturdy, beach-ready cotton feel rather than a slippery drape. The full pattern is free on the Originally Lovely blog, while an ad-free PDF is sold separately on Ravelry and Etsy, so follow the blog version for the free one. As a sarong its triangular point falls beautifully at one side, and as a scarf it is just as pretty over a sundress. This is a wonderful stash-busting project if you have cotton yarn waiting for a purpose.

11. A Long Treble Wrap From Maui for Scarf, Shawl or Sarong
The Island Summer Wrap from Pink Plumeria Maui is another convertible piece, and this one comes with a proper island pedigree. Worked in treble crochet increases and decreases with Coboo yarn on a G 4 mm hook, it finishes at roughly 15 inches wide by 96 inches long — a long, lean rectangle you can wind around your waist as a sarong, drape as a shawl, or loop as a scarf. The designer rates it Easy, and the treble fabric is light and airy enough for the hottest days while still giving real coverage. The pattern is free on the Pink Plumeria Maui blog, with an ad-free PDF sold separately in the shop and on Ravelry, so again the blog is your free route. I love this one in a tropical print-effect yarn or a solid hibiscus pink, worn long and loose over a swimsuit with a straw hat.

12. One Skein of Cake Yarn Becomes a Pareo
Light and Joy Designs calls this one a shawl, a wrap, a pareo and a beach sarong all at once, and honestly all four descriptions fit. The Pretty Little Thing Shawl is made from a single skein of cake yarn on a J 6.0 mm hook, so the colour changes happen by themselves as you crochet, giving you a gorgeous gradient without ever changing balls. The full pattern is free on the designer's blog, with an ad-free PDF sold separately on Ravelry, Etsy and LoveCrafts, so the blog version is the free path. From just one skein, it is also one of the most budget-friendly pieces here, and it packs down to almost nothing. Choose a cake yarn with a sunset gradient and let the colours do the styling for you.

13. A Gradient Wrap Skirt With a Matching Bikini
Sys Fredens' Bella Wrap Skirt from Hobbii is the most polished wrap skirt in this collection, and it comes with a delightful bonus: there is a matching Bella Bikini set in the same gradient yarn, so you can crochet a coordinated beach outfit from one pattern family. The skirt itself is worked in gradient Sultan yarn on a 3.5 mm hook in sizes from XS and S right up to XL and XXL, and the wrap construction ties at the waist for an adjustable fit. It is a free Hobbii pattern, available as a free download from the Hobbii site, and the gentle colour fade gives it a ready-to-wear look that belies its handmade origins. Pair the finished skirt with the matching bikini top and an open linen shirt, and you have a resort outfit that looks straight out of a boutique. This is the one to make when you want your crochet to look its most professional.

14. A Seamed Pull-On Beach Skirt for No-Fuss Mornings
Here is my honest-flag moment: Jenny and Teddy's Easy Beach Skirt is not a tie-on wrap at all, but a seamed pull-on beach skirt, and I am including it because it does the sarong's job with zero fuss. The design starts with a ribbed band of about 26 inches, continues in a fancy lace stitch for roughly 12 inches of length, and is seamed up the sides with one end left open — you simply step into it and go. The full pattern is free on the Jenny and Teddy blog with a video tutorial to help, and the lace stitch keeps it breathable enough for the hottest afternoons. For anyone who finds tying a wrap fiddly, or who wants a cover-up that stays put while chasing children along the shoreline, this pull-on shape is genuinely the more practical choice. Make it in white cotton and it will match every swimsuit in your drawer.

15. A Skirt-or-Top You Work in Rounds With a Woven Tie
Our second Aprile Mazey design is another honestly-flagged cousin: the Beach Cover Up Skirt or Top is a pull-on piece worked in rounds, not a tie wrap, but its wearability earns it a spot. It is sized for ladies 0 to 8 with customizing instructions included, measures about 16 inches long by 40 inches around, and is worked in number 10 crochet thread on an E 3.5 mm hook in single, half double and double crochet, finishing with a woven tie for a neat waist detail. It is a free Ravelry download, and the two-way design — skirt over your swimsuit or top on its own — makes it one of the hardest-working pieces here. The fine thread gives it a delicate, lacy feel that belies how quick it is to make. Try it in a soft ecru for a piece that goes from beach to lunch without missing a beat.

16. Linked Flowers and a Stretchy Drawstring Waist
The Kalimah Beach Skirt from Krazy Kabbage is built from linked flowers, which gives it a pretty, almost jewellery-like texture that photographs beautifully. Its most practical feature is the stretchy waistband with belt and drawstring holes, so you can adjust the fit exactly and never worry about it slipping while you walk along the shore. The full pattern is free on the Krazy Kabbage blog, while an ad-free PDF is sold separately on Ravelry, so the blog is your free route. This is another pull-on beach skirt rather than a tie wrap, and I flag it as such, but the flower construction makes it feel special in a way a plain skirt never could. In a bright coral or a soft seafoam it is the kind of cover-up that gets compliments from strangers on the boardwalk.

17. The Wrap Skirt Half of a Swimsuit Cover-Up Set
Hay Hay Crochet's Simple Tie Swimsuit Coverup is a two-piece set, and the part I want you to notice is the wrap skirt half, which is a genuine made-to-fit wrap. The skirt section is worked as filet panels seamed to about 12 to 15 rows high depending on your size, with long ties chained to 76 stitches, so you wrap it around your waist and knot it just like a sarong. The full set pattern is free on the Hay Hay Crochet blog with a video tutorial, and because it is written made-to-fit rather than to fixed sizes, it adapts beautifully to any body. If you crochet the matching top too you have a complete coordinated cover-up, but the wrap skirt stands perfectly well on its own over any swimsuit. Lightweight, stretchable, breathable cotton is the designer's recommendation, and I agree — this is a piece you will forget you are wearing, in the best way.

18. A Cover-Up Written Off Your Own Measurements
Jessie Rayot's Nettie's Super Simple Cover Up is the pattern for anyone who has ever been frustrated by a size chart, because it is written entirely off your own waist and hip measurements. You start by making a tie string — your waist measurement multiplied by two, plus 36 inches — then work the skirt section from markers placed on that string, so the finished piece fits your body and nobody else's. It can be worn as a skirt or as a dress-style cover-up, it is made in Lion Brand 24/7 yarn on a US G 4.00 mm hook, and the full pattern is free on the Jessie At Home blog with a video link for the stitch. An optional beaded row adds a touch of sparkle if you fancy it, and the whole thing is rated easy. This is the cover-up I would make for a friend as a gift, because the made-to-measure approach means it will fit her perfectly even if I only know her approximate size.

19. A Shimmering Skirt That Doubles as a Poncho
Doris Chan's Shimmer Skirt or Poncho is the dressiest convertible in this collection, and it comes from the Red Heart free pattern library via Yarnspirations. Worked in Red Heart Shimmer worsted weight yarn on a 5.5 mm I hook, it uses a shell stitch that gives the fabric a subtle sparkle, and a waistband elastic casing keeps the skirt version sitting exactly where it should. Sizes run from XXS right up to 2XL with a finished length of about 23 inches, and the clever part is the convertible construction: wear it as a flowy skirt, or flip it into a cosy poncho for cooler evenings. The pattern is a free download from Yarnspirations with no sign-up required at all. In the designer's chocolate colourway it looks far more expensive than the yarn cost suggests — the sarong-adjacent piece for a smart seaside dinner.

20. A Mesh Wrap You Learn Entirely by Video
We are finishing with something a little different, and I want to label it clearly: this last idea is a video tutorial rather than a written pattern, so it belongs to you if you learn best by watching rather than reading. Elyse Crochets walks you step by step through an easy mesh skirt and swimsuit wrap, made to fit any size, using worsted weight 3 yarn and a 5 mm hook, with optional tassels at the finish. The mesh stitch is gloriously simple — mostly chains and single crochet worked into loops — and because you size it to your own body as you go, there is no size chart to fight with. The tutorial is free on YouTube, and the finished wrap is lightweight, stylish and perfect for summer, worn as a skirt, a swim cover-up or a layered beach accessory. If written patterns ever make you nervous, press play on this one and crochet along at your own pace.

Conclusion
And that is twenty sarongs, wraps and beach skirts, my friend — true tie-on wraps in lace and shells, triangle shawls that moonlight as sarongs, pull-on skirts for no-fuss mornings, and one friendly video tutorial for the visual learners among us. If you are new to wearables, start with the Cotton Beach Sarong or the fringed triangle; if you want a showpiece, the asymmetrical lace triangle or the gradient Bella wrap skirt are calling your name. My one practical tip: choose cotton or a cotton blend for anything meeting sand and salt water, and block your finished piece gently so the lace opens up properly. A sarong is the rare crochet project that is both the simplest thing in your beach bag and the one everyone asks about.
Now tell me — are you team true tie-on wrap or team pull-on beach skirt, and which of these twenty is going on your hook first? I read every comment, and I cannot wait to see your makes!
