Boho Granny Square Vest Crochet Pattern | Women’s Handmade Crochet Top

There’s something deeply satisfying about wearing a garment you’ve made with your own two hands, and a boho granny square vest is one of those pieces that feels both nostalgic and completely on trend. Whether you’re heading to a festival, layering over a flowy sundress, or just adding a handmade touch to your everyday wardrobe, this style of crochet top has become a staple in the handmade fashion world. In this post, I’m sharing everything you need to know to crochet your own granny square vest — from the materials you’ll need to a full written pattern, assembly tips, and ideas for customizing the finished piece to suit your style.

Why Granny Square Vests Are Having a Moment

Granny squares have been around for generations, beloved by crocheters for their portability, versatility, and the way they let you work in small, satisfying sections rather than committing to a large, unwieldy piece of fabric. But the modern revival of the granny square has pushed it far beyond the lap blankets and potholders of decades past. Today, crochet designers are constructing entire garments from these small motifs — and the vest is one of the most popular applications.

Part of the appeal is practical. Because a vest is made up of flat, square motifs that get sewn or joined together, there’s very little shaping required. You’re not increasing and decreasing to form armholes or calculating sleeve caps. The structure comes from the arrangement of squares, making it an ideal project for someone who wants to make a wearable garment without diving deep into garment construction techniques.

The aesthetic appeal is just as strong. A granny square vest has that effortlessly boho look that pairs beautifully with wide-leg linen pants, denim cutoffs, maxi skirts, or a simple fitted turtleneck for autumn layering. It lives at the intersection of vintage charm and modern handmade style, and because you can choose any color palette you love — from earthy neutrals to rainbow brights — every vest ends up as a truly one-of-a-kind piece.

Materials You’ll Need

Before you start crocheting, gather everything you need so the process flows smoothly from beginning to end.

Yarn: You’ll want a DK or worsted weight yarn in your chosen colors. For a classic boho look, consider earthy tones like terracotta, mustard, cream, sage, and rust — or go with a single neutral color for something more understated. A cotton or cotton-blend yarn is ideal for spring and summer vests because it drapes well and breathes. For a fall or winter version, a wool or acrylic blend adds warmth and a cozy texture. Plan on roughly 800–1,200 yards of yarn depending on your size and square count.

Hook: A 4.0 mm (G/6) hook works well with DK weight yarn, while a 5.0 mm (H/8) hook is better suited to worsted weight. Always swatch and adjust as needed based on your gauge.

Tapestry needle: You’ll need this for weaving in ends and for joining your squares together if you choose a sewn join.

Scissors: A sharp, small pair makes trimming yarn ends clean and easy.

Stitch markers: Optional, but helpful for marking the beginning of rounds or key joining points.

Blocking mats and pins: Blocking your granny squares before assembly makes a significant difference in the finished look. Flat, even squares are much easier to join and create a more polished final garment.

Gauge and Sizing

Gauge matters more for garments than it does for home goods like blankets or dishcloths, so take time to make a test square and measure it before casting on your full project.

Gauge: Each finished granny square should measure approximately 4 inches by 4 inches (10 cm x 10 cm) after blocking with worsted weight yarn and a 5.0 mm hook.

The vest pattern below is designed for a women’s size medium, with a finished bust measurement of approximately 38–40 inches. The pattern is easy to resize: each square adds approximately 4 inches to the width or length, so you can add or subtract squares to reach your desired fit. A larger square worked to 5 inches or 6 inches each will also change the overall proportions significantly.

The basic layout for the size medium uses the following square counts:

• Front panel: 4 squares wide, 5 squares tall (20 squares total)
• Back panel: 4 squares wide, 5 squares tall (20 squares total)
• Total squares: 40 granny squares

The Granny Square Pattern

This is a classic 4-round granny square with a slight modern update — the corners are slightly more open, giving the finished vest a lovely airy quality.

Foundation ring: Chain 4, slip stitch to the first chain to form a ring.

Round 1: Chain 3 (counts as first double crochet), work 2 double crochets into the ring, chain 2, [work 3 double crochets into the ring, chain 2] three times, slip stitch to the top of the beginning chain-3 to join. You now have four clusters of 3 double crochets separated by corner chain-2 spaces.

Round 2: Slip stitch into the next two stitches and into the corner chain-2 space. Chain 3, work 2 double crochets into the same space, chain 1, [work 3 double crochets, chain 2, work 3 double crochets] into the next corner space, chain 1. Repeat the bracket sequence two more times, then work 3 double crochets, chain 2 back into the starting corner space. Chain 1, slip stitch to the top of beginning chain-3 to join. You now have two clusters per side and a chain-2 corner space.

Round 3: Slip stitch to the corner chain-2 space. Chain 3, work 2 double crochets into the same space, chain 1. [Work 3 double crochets into the next chain-1 space, chain 1]. Work [3 double crochets, chain 2, 3 double crochets] into the corner chain-2 space, chain 1. Repeat the bracketed side sequence, then corner sequence, around all four sides. Slip stitch to join.

Round 4: This is your border round, worked in a single contrasting color if desired. Slip stitch to the corner chain-2 space. Chain 3, work 2 double crochets, chain 2, work 3 double crochets into the corner space. Chain 1, work 3 double crochets into each chain-1 space across the side, chain 1, work [3 double crochets, chain 2, 3 double crochets] into the corner. Repeat from * around all four sides. Slip stitch to join, fasten off, and weave in ends.

Block each square after completing it or all at once before joining. Pin them to your blocking mats, mist lightly with water, and allow to dry completely.

Joining Your Squares

There are several methods for joining granny squares, and the one you choose will affect both the look and the drape of the finished vest.

Flat slip stitch join (my recommendation for this vest): Hold two squares with wrong sides together and use your hook to slip stitch through the back loops of both squares simultaneously. This creates a subtle raised seam on the right side that actually adds a beautiful texture detail to a boho-style garment.

Flat single crochet join: Similar to the slip stitch join but creates a slightly thicker, more defined seam. Works well with thicker yarns and gives the vest a more structured, patchwork appearance.

Whip stitch join: Using a tapestry needle and a length of yarn, whip stitch through the outer loops of each square. This is the flattest join and creates the most invisible seam. It’s a good choice if you want your squares to speak for themselves without any visible joining lines.

Join-as-you-go (JAYG): If you prefer to avoid assembly entirely, you can join each new square to the existing piece on the final round. This technique takes a bit of practice to understand, but once you get the rhythm it’s extremely satisfying because you end up with a fully joined panel without any extra sewing step.

Lay all your blocked squares out on a flat surface before joining them. Arrange them in a pattern you love — you might alternate colors in a checkerboard arrangement, create a gradient from light to dark, or go for a deliberately random, scrappy multicolor mix.

Assembling the Vest

Once all your squares are joined into two panels (front and back), assembling the vest is straightforward.

Shoulder seams: Hold the front and back panels with right sides together. Join the top two squares on each side with your chosen join method, leaving the center squares open for the neckline. For a size medium, joining the outer one square on each side creates shoulder seams of approximately 4 inches. If you prefer wider shoulders, join two squares on each side.

Side seams: With right sides together, join the side edges of the front and back panels, leaving the top 8–10 inches open on each side to form the armhole openings. Because this is a vest, there are no sleeves — those open edges become the armholes. You can leave them as they are for a more relaxed, flowy look, or add a crochet border around each armhole for a cleaner finish.

Finishing the neckline: Work a simple single crochet border around the neckline opening, working approximately one single crochet per stitch or row edge and making sure the total stitch count is a multiple that keeps the neckline flat without pulling or flaring. You can also work a reverse single crochet (crab stitch) as a final border round for a nicely textured edge.

Finishing the hem: Work a border along the bottom edge of the vest in the same way as the neckline — a round or two of single crochet followed by a reverse single crochet for a tidy, stable finish.

Customizing Your Vest

One of the greatest things about a granny square vest is how infinitely customizable it is. Here are some ideas for making this pattern completely your own.

Play with square size. Working larger squares — say, 6 inches each — means you need fewer squares overall and the vest will have a bolder, more graphic look. Smaller squares, around 3 inches each, create a denser, more intricate fabric with a fine, detailed texture.

Add fringe. Cut lengths of yarn about 10 inches long, fold them in half, and use a crochet hook to pull them through the bottom edge of the vest for a festival-ready fringe trim. This detail instantly amplifies the boho vibe.

Try a different color palette. Monochromatic vests in shades of cream, ivory, and white feel elegant and timeless. A maximalist rainbow palette feels joyful and retro. Earthy terracotta, sand, and olive tones read as modern and on-trend. A black, white, and grey combination feels graphic and contemporary.

Use different stitch patterns for variety. Instead of making all 40 squares identical, try alternating between the classic granny square and a solid granny square (worked in all double crochets with no chain spaces) or a sunburst square with a raised center. Mixing motif types while keeping a consistent color palette adds visual interest without chaos.

Add buttons or ties. If you want a more fitted look, you can add a button or a ribbon tie at the center front. Work a simple chain loop at the corner where two squares meet on the front panel and sew on a complementary button on the opposite side.

Lengthen it into a duster. Adding more rows of squares to the length of both the front and back panels turns this vest into a long boho duster that hits at hip or thigh length — an incredibly versatile layering piece.

Tips for a Beautiful Finished Vest

A few extra details can make the difference between a vest that looks handmade in the best possible way and one that looks a little unfinished.

Weave in all your ends carefully and securely. With granny squares, there are a lot of yarn tails, and loose ends will work themselves free over time. Using a tapestry needle to weave each tail in at least two directions (forward and then back through the same yarn) gives it a secure hold.

Block generously and don’t skip this step. Unblocked granny squares curl and pucker. After blocking, they lie flat and even, and your finished vest will drape beautifully instead of looking stiff and lumpy.

When working your border rounds at the neckline and armholes, try the vest on (or measure it against yourself) before you fasten off. It’s easy to add an extra round if you want more coverage, or to stop one round earlier if the neck feels too high.

Consistent tension throughout your squares will make assembly much easier. If your tension varies significantly from square to square, some will end up noticeably larger or smaller, and joining them will require a lot of fudging. If you notice your tension drifting, take a break and come back to the project fresh.

Caring for Your Handmade Vest

Once you’ve invested the time and love into making this vest, you’ll want it to last. Most cotton and cotton-blend vests can be hand washed in cool water with a gentle soap and laid flat to dry. Avoid wringing or twisting the fabric, which can distort the squares and stretch the joins. If your yarn is machine washable, use a delicate cycle in a mesh laundry bag and still lay flat to dry rather than machine drying, which can cause shrinkage and distortion.

Store your vest folded rather than on a hanger. Because crochet fabric is more elastic than woven fabric, hanging a crochet garment over time can cause it to stretch out of shape, especially at the shoulders.

A Note on Making It Your Own

Patterns are starting points, not rules. If you want to make this vest longer or shorter, wider or more fitted, in a single color or twenty colors, with fringe or without — do it. The most beautiful handmade garments come from crocheters who trust their own taste and aren’t afraid to deviate from the instructions when something doesn’t feel right. This pattern gives you the framework. What you do with it is entirely up to you.

The boho granny square vest is more than just a crochet project. It’s a piece of wearable craft that carries the hours of your attention and care in every stitch. Wear it proudly, make another one as a gift, and share your finished work with the crochet community — there’s always someone just discovering granny squares who needs to see what’s possible.

Happy crocheting.
