Free Summer Crochet Beach Cover Up Sarong Pattern

There is something deeply satisfying about walking from your beach towel to the snack bar wrapped in something you made yourself. A crochet beach cover up sarong is one of those projects that feels indulgent but is actually quite practical, wearable, and fast to finish if you pick the right yarn and stitch. This free pattern will walk you through everything you need to know to make a beautiful, breezy sarong that works as a cover up over a swimsuit, a lightweight wrap for a summer evening, or even a stylish layering piece for a festival or outdoor concert.

Whether you are a beginner looking for a manageable summer project or an experienced crocheter wanting something quick and satisfying between more complex makes, this pattern is designed to be flexible, forgiving, and fun. You can finish it in a weekend, customize the length and width to fit your body, and choose any cotton or linen yarn in your favorite color palette. Let’s get into everything you need to know.

Why Crochet a Beach Sarong?

Before we dive into the pattern itself, let’s talk about why a crochet sarong is such a great summer project. First, it is genuinely quick. Because a sarong is essentially a large rectangle, you are not shaping armholes, picking up stitches, or seaming sleeves together. You work back and forth (or in a direction that suits your preference) until you reach your desired dimensions. That simplicity makes it ideal for beginners who want a finished wearable piece without the complexity of garment construction.

Second, it is endlessly customizable. Want more coverage? Add length. Prefer something hip-length and flirty? Stop earlier. Want a bold solid color? Go for it. Want to practice your color blocking or gradient yarn skills? A sarong is the perfect canvas. The rectangular format means you can experiment freely.

Third, cotton and linen yarns — the best choices for a beach cover up — are absolutely beautiful to crochet with in warmer months. They have a natural breathability and drape that synthetics can’t quite replicate, and they wash and dry easily after a day at the beach or the pool. Many cotton yarns are also budget-friendly, making this a low-cost project in addition to a satisfying one.

Materials You Will Need

For this pattern, you will need the following supplies:

Yarn: Approximately 600–900 yards of DK or light worsted weight cotton or cotton-blend yarn. The exact yardage depends on the final size you choose. A 100% cotton yarn or a cotton-linen blend works beautifully for drape and breathability. Good options include Lion Brand 24/7 Cotton, Paintbox Simply DK Cotton, Paintbox Simply Aran Cotton, or similar budget-friendly options. For a more luxurious feel, Cascade Ultra Pima or Rowan Cotton Cashmere are lovely choices. Choose whatever color speaks to you — classic white and cream are perennially popular, but a rich terracotta, sage green, dusty blue, or warm sand color can look stunning.

Hook: A 5.0 mm (US H/8) crochet hook is recommended for DK weight yarn. If you are using light worsted, try a 5.5 mm (US I/9) hook. Adjust based on your gauge swatch results.

Notions: A yarn needle for weaving in ends, scissors, and a tape measure. Optional: stitch markers can help you keep track of your row counts.

About Sizing

This pattern is written to be fully adjustable. A standard sarong for a size small to medium will measure approximately 42 inches wide by 24 inches long. For a longer cover up that reaches mid-thigh or knee length, aim for 32 to 36 inches in length. For a maxi-length wrap that falls to the ankle, work until the piece measures 48 to 52 inches in length.

To customize the width, simply adjust your starting chain. The pattern uses a multiple of 4 stitches plus 3 for the stitch repeat, so you can easily add or subtract stitches in increments of 4 to widen or narrow the piece. Always make a gauge swatch before starting to ensure your finished dimensions will match your intentions.

Gauge

14 stitches and 8 rows in double crochet using a 5.0 mm hook equals approximately 4 inches by 4 inches with DK weight cotton yarn. Because this is a wearable with no fitted seams or armhole shaping, gauge is primarily important for getting the correct finished dimensions. If your piece is coming out too small, go up a hook size. If it is coming out too large, go down a hook size.

The Stitch Pattern: Open Shell Stitch

This sarong uses an open shell stitch that creates a lacy, airy fabric perfect for beach and pool days. It is simple enough for a confident beginner (one who knows how to chain, single crochet, double crochet, and skip stitches) but creates a result that looks impressively textured and professional.

Foundation: Chain a multiple of 4 stitches plus 3.

For a standard sarong that is approximately 42 inches wide, chain 147 (that is 36 pattern repeats plus 3 extra).

Row 1 (right side): Single crochet in the second chain from hook and in each chain across. Turn.

Row 2: Chain 3 (counts as first double crochet), skip the next 2 stitches, work 5 double crochets in the next stitch (this is your first shell), skip 2 stitches, single crochet in the next stitch. Continue across the row, repeating: skip 2, 5 double crochets in next stitch, skip 2, single crochet in next stitch. End with a single crochet in the last stitch. Turn.

Row 3: Chain 1, single crochet in the first stitch. Work 5 double crochets in the single crochet from the previous row (the one between the shells), then single crochet in the center stitch of each 5-double crochet shell across the row. End with single crochet in the top of the turning chain. Turn.

Row 4: Chain 3, work 2 double crochets in the first single crochet (half shell to start), single crochet in the center double crochet of each shell, work 5 double crochets in each single crochet between shells, end with 3 double crochets in the last single crochet (half shell to finish). Turn.

Repeat rows 3 and 4 until your piece reaches the desired length, ending on a row 3 repeat for a tidy finish. Then work one final row of single crochet across all stitches to create a clean edge.

Do not worry if this feels a little confusing at first — the stitch pattern has a visual logic that becomes very clear once you have worked two or three repeats. You will quickly see how the shells stack and alternate, and the rhythm becomes almost automatic.

Finishing the Edges

Once your main rectangle is complete, you have a few options for finishing the edges. The simplest approach is to work one round of single crochet around the entire perimeter of the sarong, working 3 single crochets in each corner to keep the fabric flat. This creates a clean, tidy border without adding bulk or visual complexity.

If you want something a little more decorative, you can add a shell border. After the initial round of single crochet, work a second pass with small shells: skip 2, 5 double crochets in next stitch, skip 2, slip stitch in next stitch, across each long side. This echoes the open shell stitch of the body and creates a beautifully cohesive finished piece.

Another lovely option for the short ends of the sarong is a simple fringe. Cut pieces of yarn approximately 10 to 12 inches long, fold each piece in half, insert your hook through an edge stitch, pull the folded loop through, then pull the two tails through the loop and tighten. Space your fringe evenly across each short end. Fringe gives the sarong an effortlessly boho look that suits a beach setting perfectly.

How to Wear a Crochet Sarong

One of the best things about a sarong is how many ways you can style it. The classic wrap is to hold the fabric behind you and tie the two top corners in a knot at one hip — this creates a skirt wrap that works beautifully over a bikini. You can also wrap it around your body and tuck one corner into the top edge across your chest for a strapless, dress-like silhouette.

For a more modest cover up, try draping the sarong over one shoulder like a shawl and tying it at the opposite hip. This creates an asymmetric, toga-inspired look. You can also fold the sarong in half and wear it as a shorter skirt, which is particularly nice if you made a longer version and want a quick change for dinner after the beach.

Because crochet fabric has some stretch, a crochet sarong moves and drapes differently from a woven fabric one. This actually works in its favor — the fabric will cling gently and move with you rather than staying completely stiff, which gives it a relaxed, lived-in elegance.

Yarn Color Inspiration

Choosing your yarn color is one of the most fun parts of this project. Here are some ideas to spark your imagination.

Classic white or cream is always stunning for a beach cover up. It photographs beautifully, pairs with any swimsuit color, and has a timeless, airy quality. Just know that white cotton can be slightly see-through when wet, so wear it with a swimsuit you feel confident in.

Warm terracotta, rust, or burnt orange tones have been enormously popular in recent seasons and look gorgeous against tanned skin. They also pair wonderfully with turquoise or navy swimwear.

Sage green, dusty rose, and warm taupe are quieter, more neutral choices that feel sophisticated and easy to style. These colors work especially well if you are planning to wear the sarong not just at the beach but also to outdoor dinners or summer evening events.

If you want to make the project more of a showpiece, try working it in a gradient yarn or creating your own color transition by changing to a new skein in a harmonious color at regular intervals. A fade from deep cobalt blue to pale sky blue, or from hot coral to soft peach, would be absolutely stunning in this open shell stitch.

Tips for Success

A few practical notes before you cast on:

Wash your yarn before you begin if you are concerned about color bleeding or shrinkage, especially with deeply saturated cotton yarns. This is good practice for any garment or accessory that will be worn against the skin or near water.

Keep your tension consistent throughout. Because the open shell stitch creates a lacy fabric, inconsistent tension will be more noticeable here than in a denser stitch. Take your time in the first few rows to find a rhythm that feels comfortable.

If you run out of yarn mid-row, try to join a new skein at the beginning of a row rather than in the middle. This makes it much easier to weave in your ends cleanly and invisibly.

When blocking your finished sarong, wet blocking will give you the best results with cotton yarn. Soak the piece in cool water for 20 minutes, gently squeeze out excess water without wringing, lay flat on a clean towel, shape to your desired dimensions, and allow to dry completely before wearing. Blocking opens up the lace pattern beautifully and evens out any inconsistencies in tension.

Store your sarong folded flat or rolled to avoid stretching the delicate open stitch fabric. Cotton does not have the elastic memory of wool, so it can stretch out of shape if hung for long periods.

Frequently Asked Questions

Can a beginner make this sarong? Yes, absolutely. If you know how to chain, single crochet, and double crochet, you have all the skills you need. The open shell stitch looks complicated but follows a simple, rhythmic pattern that becomes intuitive quickly.

How long will this project take? Most crocheters working at an average pace can complete a standard-sized sarong in two to four days of casual crocheting, or a single dedicated weekend.

Can I use a different yarn weight? Yes, you can. If you use worsted weight cotton, your finished piece will be slightly denser and heavier, which some people prefer. Fingering or lace weight cotton will produce a very delicate, see-through fabric. DK or light worsted gives the best balance of drape and coverage for most purposes.

Can I make this as a gift? It is a wonderful gift idea. A personalized handmade sarong in someone’s favorite color is a thoughtful, unique summer present that most people would not think to buy for themselves.

Is this pattern truly free? Yes — the full pattern is written out above. You are welcome to make as many sarongs as you like for personal use. If you sell finished items made from this pattern, please use your own handmade goods and credit the pattern accordingly.
