Crochet Granny Square Top Pattern | Boho Summer Crochet Top

There is something timeless about a granny square. It is one of those motifs that has traveled through generations of crafters, from your grandmother’s living room to the runways of contemporary fashion, and it never seems to lose its charm. When you combine that classic motif with the breezy, free-spirited energy of a boho summer top, you get something truly special — a garment that feels handmade in the best possible way, one that drapes beautifully over a swimsuit or pairs effortlessly with high-waisted linen shorts.

This crochet granny square top pattern is designed with wearability in mind. It is beginner-friendly enough for someone who has made a few granny squares before, yet interesting enough to keep an experienced crocheter engaged from start to finish. Whether you are making this for yourself, gifting it to a friend, or adding it to your Etsy shop, you are going to love how this top comes together.

Let’s dive in.

Why Granny Square Tops Are Having a Moment

Walk through any festival, farmers market, or coastal town in summer and you will spot them — granny square tops, vests, and cardigans worn with easy confidence. This resurgence is not accidental. The crochet renaissance of the past several years has brought a whole new generation of makers to the craft, and boho fashion has given them the perfect canvas to show off their work.

What makes a granny square top so appealing is its versatility. The construction method — joining individual motifs rather than working in the round or in rows from a single piece — means you can customize the sizing relatively easily. Add a square here, remove one there, and the fit changes to suit your body. For curvy makers and anyone who has ever struggled to adapt a standard top pattern, this is genuinely liberating.

There is also the color play. A granny square top can be made in a single colorway for a sleek, modern look, or in a riot of colors for that classic bohemian patchwork feel. You can carry one color across all your squares and change only the border, or go completely scrappy and use up every last bit of your yarn stash. The pattern adapts to your vision.

Materials You Will Need

Before you cast on — or rather, make your slip knot — gather everything you need so the project flows smoothly.

Yarn: Choose a DK weight or light worsted weight cotton yarn for a summer top. Cotton is the queen of warm-weather crochet. It is breathable, has a lovely drape, and holds its shape well. Brands like Lion Brand 24/7 Cotton, WeCrochet Dishie, or Paintbox Yarns Simply DK Cotton are excellent choices. For a top sized small to medium, plan on approximately 800 to 1,000 yards. For a medium to large, budget around 1,000 to 1,200 yards.

Hook: A 4mm (US G/6) or 4.5mm (US 7) crochet hook works beautifully with DK or light worsted cotton. Check your gauge swatch before committing to a hook size.

Notions: Scissors, a yarn needle for weaving in ends, stitch markers, and a measuring tape. If you want to add a ribbon or drawstring at the waist or neckline, have that ready as well.

Gauge: With a 4mm hook and DK cotton, one finished granny square should measure approximately 4 inches by 4 inches after blocking. With a 4.5mm hook, aim for 4.5 inches by 4.5 inches. Gauge really matters for wearables, so please do take the time to make a test square and measure it.

Understanding the Construction

This top is made entirely from individual granny squares that are joined together using the join-as-you-go method (JAYG) or seamed together after all motifs are complete. Either approach works, and both are described below.

The basic layout for a size small/medium top requires 20 squares: 10 for the front panel and 10 for the back panel. Each panel is arranged in a 2-wide by 5-tall grid. The two panels are joined along the sides and shoulders, leaving openings for the armholes and neckline. A simple ribbed or chain border finishes everything off.

For a size medium/large, you will use 24 squares total: 12 per panel, arranged in a 3-wide by 4-tall grid. This gives a wider silhouette.

For a plus-size version or a more oversized boxy fit, go to 28 squares: 14 per panel, arranged in a 2-wide by 7-tall grid. The extra length adds a lovely tunic-style coverage.

The Classic Granny Square: Step-by-Step Instructions

If you already know how to make a classic granny square, feel free to skip ahead. If you want a refresher or are making your first one, here is a detailed breakdown.

Abbreviations:

ch = chain, sl st = slip stitch, dc = double crochet, sp = space, rep = repeat, rnd = round

Foundation Ring: Make a magic ring, or chain 4 and join with a slip stitch to form a ring.

Round 1: Chain 3 (counts as first dc), work 2 dc into the ring, chain 2. Work 3 dc into the ring, chain 2. Repeat from two more times. Join with a slip stitch to the top of the beginning chain 3. You now have four clusters of 3 dc with a ch-2 corner space between each cluster. (4 clusters, 4 corner spaces)

Round 2: Slip stitch into the corner ch-2 space. Chain 3, work 2 dc in the same space, chain 1. Work 3 dc, chain 2, and 3 dc all in the next corner ch-2 space (this forms the first full corner). Chain 1, work 3 dc in the next ch-1 side space, chain 1. Work 3 dc, chain 2, and 3 dc in the next corner ch-2 space. Repeat from around, ending with chain 1. Join with a slip stitch to the top of the beginning chain 3. (8 clusters total)

Round 3: Slip stitch into the corner ch-2 space. Chain 3, work 2 dc in the same space, chain 1. Work 3 dc in the next ch-1 side space, chain 1. Work 3 dc, chain 2, and 3 dc in the next corner ch-2 space, chain 1. Repeat from around, working 3 dc clusters into each ch-1 side space and full corners into each ch-2 corner space. Join with a slip stitch. (12 clusters total)

Round 4 (Border Round): Work in the same manner, adding one more cluster per side. This round is where you can introduce a contrasting color for a pop of interest. Join all rounds neatly and fasten off. (16 clusters total)

You want your finished square to lie flat and have clean, even corners. If your corners are pulling up or your sides are buckling, go up or down a hook size.

Joining Your Squares

There are two popular methods for joining granny squares, and both give beautiful results.

Method 1 — Flat Slip Stitch Join (worked with WS together): Hold two squares with wrong sides facing each other. Using a new length of yarn and your hook, insert through both outer loops of the corresponding stitches on each square and slip stitch across. This creates a visible ridge on the right side that many makers love for its textural, boho quality.

Method 2 — Join As You Go (JAYG): When working the final border round of each square, join it to a completed square by replacing the chain-2 corner spaces and chain-1 side spaces with single crochets worked into the corresponding spaces of the neighboring square. This method requires a bit more planning but eliminates seaming entirely and gives a smooth, nearly seamless join.

Whichever method you choose, consistency is key. Always join squares with the same side facing you so your right-side remains uniform across the whole top.

Assembling the Top

Once all your squares are made and joined into two rectangular panels, it is time to put the top together.

Joining Panels at the Sides: Hold the front and back panels with right sides together. Using a slip stitch join or your preferred seaming method, join along both side edges. Leave approximately 7 inches open at the top of each side seam for the armhole openings. For a size small, 6.5 inches is usually enough; for a large or extra large, you might prefer 7.5 to 8 inches.

Joining Panels at the Shoulders: Join the front and back panels at the shoulders, leaving the center open for the neckline. The width of the neckline opening is a matter of personal preference. For an off-the-shoulder or wide neckline, leave the center 8 to 10 inches open. For a more modest crew-style neckline, leave only 5 to 6 inches.

Turn the top right side out and try it on (or hold it up to yourself) before committing to any finishing details. This is your chance to adjust before you weave in all those ends.

Finishing Touches That Elevate the Design

The finishing is where a granny square top goes from a collection of joined motifs to a polished, wearable garment. Do not skip these steps.

Neckline Border: Using your main color or a contrasting accent color, work a round of single crochet evenly around the neckline opening. Then work a round of reverse single crochet (also called crab stitch) for a neat, professional edge. Alternatively, a simple chain loop edging creates a delicate, feminine finish that suits the boho aesthetic beautifully.

Armhole Borders: Repeat the same border treatment around each armhole opening. Keep your stitch count consistent so the armholes match.

Hem Border: At the bottom of the top, work 2 to 3 rounds of single crochet, then finish with reverse single crochet or a shell edging. A shell edging (work 5 dc in the same stitch, skip 2, sc, skip 2, and repeat) adds a flirty, wavy finish along the hem that looks stunning in person.

Blocking: This is non-negotiable for cotton garments. Wet blocking is the most effective method. Submerge your finished top in cool water, gently squeeze out the excess, then lay it flat on a blocking mat and pin it to your desired dimensions. Let it dry completely — this can take 12 to 24 hours depending on your climate. Blocking evens out uneven tension, opens up the lace of the squares, and gives the garment a drape and polish that no amount of careful crocheting alone can achieve.

Sizing Guide

Here is a quick reference for how to scale this pattern to different sizes. These measurements are finished garment measurements, not body measurements. Add 2 to 4 inches of ease to your actual bust measurement for a comfortable fit.

For an XS/S (30–34 inch bust), use 20 squares in a 2-by-5 grid per panel with 4-inch squares, giving a finished bust measurement of approximately 32 to 34 inches.

For an S/M (34–38 inch bust), use the same 20-square layout but work your squares to 4.5 inches using a larger hook, or add a wider border to your squares.

For an M/L (38–42 inch bust), use 24 squares in a 3-by-4 grid per panel with 4-inch squares, giving a finished bust of approximately 24 inches wide per panel, or 48 inches around.

For an L/XL and beyond (42 inches and up), use 28 or more squares per panel, adjusting the grid layout to suit your preferred length and width ratio.

Color Inspiration for Your Boho Granny Square Top

Color is one of the most personal and exciting decisions you will make in this project. Here are a few colorway ideas to spark your imagination.

A classic earthy palette of terracotta, rust, cream, and sage green feels deeply connected to the boho spirit and photographs beautifully in outdoor settings. This combination is perennially popular and never feels overdone.

For a beachy, coastal vibe, try soft ocean blues, sandy neutrals, and a touch of coral. This colorway is fresh and summery and pairs brilliantly with denim shorts or a white maxi skirt.

If you love maximalist color, go full grandmother’s flower garden and use every scrap in your stash. Tie everything together with a single neutral color for all your borders — cream, natural, or black all work wonderfully — and the result will be vibrant yet cohesive.

For a modern, minimalist take, work the entire top in a single linen-toned neutral with a slightly contrasting border. This version can actually be worn to casual workplaces or restaurants, not just the beach.

Tips for Success

Cotton yarn can feel stiff and unforgiving when you first work with it, especially compared to acrylic or wool. Maintain a slightly looser tension than you think you need. Your squares will relax and soften beautifully after washing and blocking.

Weave in your ends as you go rather than leaving them all to the end. With this many squares, the end-weaving session can be genuinely overwhelming if you put it off. Weave as you finish each motif and the final assembly will feel like a treat.

Take photographs of your progress. Granny square tops generate enormous engagement on Instagram, Pinterest, and TikTok, and your step-by-step images could help or inspire another crafter somewhere in the world.

If you are making this top to sell, price it honestly. Even working quickly, a cotton granny square top represents six to ten hours of focused work. Factor in your materials and your time at a fair hourly rate. Handmade crochet garments are worth what they cost to make.

Frequently Asked Questions

Can I use acrylic yarn for this pattern? You can, though a cotton or cotton-blend yarn will give you a much more comfortable, breathable summer top. If you do use acrylic, choose a softer, drapier one like Lion Brand Pound of Love or similar.

Can a true beginner make this top? If you can make a granny square and sew or join seams, you can make this top. The construction is simple — it is the repetition and patience that the project demands, not technical complexity.

How do I wash my finished top? Turn it inside out, use cool water and a gentle detergent, and either hand wash or use the delicate cycle on your machine. Lay flat to dry. Never put cotton crochet in a hot dryer.

What if my squares are not all exactly the same size? Slight variations are normal and will mostly disappear after blocking. If you have significant size differences, check your tension and hook consistency across squares.

Final Thoughts

A crochet granny square top is one of those projects that feels almost meditative to make. There is a quiet satisfaction in building each small square, watching your pile grow, and then seeing the whole thing come together as a wearable garment. It is patient work, but it rewards your patience generously.

Whether you make this top in a single weekend sprint or stretch it out over a few weeks of leisurely evening crocheting, the result will be something uniquely yours. No two handmade granny square tops are exactly alike, and that is entirely the point.

Pin this pattern, bookmark it, share it with your crochet group, and most importantly — make it. Your summer wardrobe is waiting.

Happy crocheting.
