Why a Granny Square Vest?
Before we dive into the pattern, let us talk about why this particular project has stood the test of time. Granny squares are endlessly versatile. They work up quickly, they are portable, and they are a fantastic way to use up yarn scraps from your stash. The beauty of a vest made from individual squares is that you can work on it in small sessions, whether you have five minutes or five hours. Each square is its own little accomplishment, and by the time you have a pile of them ready to assemble, the sense of satisfaction is enormous.
Vests are also an incredibly wearable garment. Unlike a full sweater, there is no sleeve shaping to worry about, no complicated armhole construction, and no anxiety about whether the fit will be right. A vest drapes beautifully over almost any outfit, and a granny square vest in particular has a lovely, open texture that makes it comfortable across a wide range of temperatures. It is the kind of piece that gets compliments every single time you wear it.
Materials You Will Need
Getting your materials right before you start will make the whole process much more enjoyable. Here is what you will need for this project.
Yarn: This pattern works best with a DK or worsted weight yarn. If you want a lighter, airier vest, go for DK weight. If you prefer something with more structure and warmth, worsted is your friend. You can use a single color, two complementary colors, or go full maximalist with a rainbow of scraps. For a size medium vest, plan on approximately 800 to 1,000 yards if you are working in a single color. If you are using scraps, that is a great excuse to gather every leftover skein you have and see what combinations speak to you. Cotton and cotton-blend yarns are particularly wonderful for a vest because they are breathable and have beautiful stitch definition.
Hook: For DK weight yarn, use a 4.0mm or 4.5mm hook. For worsted weight, a 5.0mm or 5.5mm hook works well. Always check your gauge before starting, because even a small difference in tension across dozens of squares can make a significant difference in the finished size of your vest.
Additional supplies: You will need a yarn needle for weaving in ends and seaming squares together, scissors, and a handful of stitch markers. A tape measure is useful for checking your gauge square and the finished dimensions as you go.
Sizing and Gauge
This pattern is written with the following finished bust measurements in mind:
Small: 32–34 inches | Medium: 36–38 inches | Large: 40–42 inches | XL: 44–46 inches | 2XL: 48–50 inches
The number of squares you need will depend on your chosen size and the size of each individual square. For this pattern, each finished granny square measures approximately 5 inches x 5 inches when worked in worsted weight yarn on a 5.0mm hook. Adjust your hook size up or down as needed to achieve this gauge. If your squares are coming out larger than 5 inches, try going down a hook size. If they are smaller, go up a size.
To achieve the gauge square, work the granny square pattern as written below through round 4, then measure. Blocking your swatch before measuring will give you the most accurate result.
Understanding the Construction
Before jumping into the pattern, it helps to understand how the vest is constructed so that the whole project makes sense as you work through it. This vest is made of individual granny squares that are seamed together to form the front panel and the back panel. The two panels are then joined at the shoulders and sides, leaving openings for the armholes. A simple single crochet edging is worked around the entire outer edge and around each armhole to give the vest a clean, polished finish.
The layout is straightforward. For a size medium, you will make 24 squares, 12 for the front panel and 12 for the back panel. Each panel is arranged in a rectangle that is 3 squares wide and 4 squares tall. The shoulder seams join the top 3 squares of the front panel to the top 3 squares of the back panel. The side seams join the outer edges of the front and back panels, leaving the armhole openings unjoined.
The Granny Square Pattern
Now for the heart of the whole project. This is a classic four-round granny square with a tidy corner construction that makes joining easy and clean.
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 double crochet throughout), work 2 double crochets into the ring, chain 2, [3 double crochets into the ring, chain 2] 3 times, join with a slip stitch to the top of the beginning chain 3. You now have four clusters of 3 double crochets and four corner chain-2 spaces. Fasten off your first color if you are changing colors here, or continue with the same yarn.
Round 2: Join yarn in any corner chain-2 space. Chain 3, work 2 double crochets into the same space, chain 1, [work 3 double crochets, chain 2, 3 double crochets] into the next corner space, chain 1. Repeat this sequence around all four corners, ending with 3 double crochets and chain 2 in the starting corner before joining to the top of chain 3. You now have two clusters on each side and one chain-2 corner space at each corner. Fasten off if changing colors.
Round 3: Join yarn in any corner chain-2 space. Chain 3, work 2 double crochets in the same space, chain 2, 3 double crochets in the same space (this completes your corner), chain 1, 3 double crochets in the chain-1 side space, chain 1, [3 double crochets, chain 2, 3 double crochets in the next corner space, chain 1, 3 double crochets in the side space, chain 1] around. Join with a slip stitch. Fasten off if changing colors.
Round 4: Join yarn in any corner chain-2 space. Chain 3, 2 double crochets, chain 2, 3 double crochets in same corner space, [chain 1, 3 double crochets in next chain-1 space] across the side, chain 1, [3 double crochets, chain 2, 3 double crochets in corner space, chain 1, 3 double crochets in each side space with chain 1 between each] around. Join with a slip stitch. Fasten off and weave in ends.
Your square should have 3 clusters on each side between the corners and a clean chain-2 corner on all four sides. Block each square lightly before assembling if you want the most even finished fabric. Even a quick spritz with water and pinning to a foam mat will make a noticeable difference.
Color Planning
One of the most fun parts of a granny square vest is deciding on your color palette. Here are a few approaches that work beautifully.
A monochromatic vest uses varying shades of the same color family, such as cream, beige, caramel, and brown, or pale pink through deep burgundy. This approach looks sophisticated and cohesive while still having visual interest.
A two-color approach, such as a cream background square with a single pop color for the rounds, is classic and graphic. It photographs beautifully and is a great choice if you want your vest to feel timeless rather than overly trendy.
A scrappy multicolor vest uses a different color combination for each square and ties them together with a single unified border color on round 4. This is my personal favorite approach because it gives every square its own personality while still making the finished garment feel like a cohesive whole.
However you plan your colors, lay out your finished squares before seaming them together and shuffle them around until the arrangement feels balanced. Trust your eye.
Assembling the Vest
Once you have all your squares made and blocked, it is time to seam them into panels. There are a few different methods for joining granny squares, and each gives a slightly different result.
The flat slip stitch join gives a nearly invisible seam and works beautifully when you want the squares to blend together seamlessly. Hold two squares with wrong sides together and slip stitch through both outer loops along the edge. This creates a flat, flexible seam on the inside.
The join-as-you-go method, where you join each new square to its neighbors during the final round, creates a very sturdy and efficient fabric but requires more planning upfront.
The whip stitch seam, worked with a yarn needle, is easy and forgiving and gives a slightly raised seam on the right side that can look intentional and decorative.
For this vest, I recommend the flat slip stitch join because it is fast, secure, and lies beautifully. Lay your squares out in the 3-wide by 4-tall grid and join them in rows first, then join the rows together. Work consistently from the same side so your seams are all facing the same direction.
Once both panels are assembled, join the front and back panels at the shoulder with two seams at the top, leaving the center open for the neck. The shoulder seams should each span one square (approximately 5 inches). Then join the side seams, leaving a gap of approximately 8 to 10 inches open at the top of each side for the armholes. The exact size of the armhole gap is a matter of fit preference, so try the vest on as you go or hold it up against a garment that fits you well.
Edging the Vest
The finishing edge makes a huge difference in how polished your vest looks when it is complete. A simple single crochet edge worked in a single color around the entire outer perimeter and around each armhole will give the vest structure and definition.
For the outer edge, join your edging yarn anywhere along the hem. Work single crochet evenly around the entire outer edge of the vest, working 3 single crochets into each outer corner and single crochet 2 together at each inner corner (such as where the armhole meets the body) to keep the edge lying flat. Work at least 2 rounds of single crochet. For a slightly more finished look, you can add a round of reverse single crochet (also called the crab stitch) as the final round. It creates a textured, rope-like border that is extremely durable and looks professional.
For the armhole edges, join your yarn at the underarm seam and work single crochet evenly around each armhole opening. Two rounds is usually enough to clean up the edge without reducing the size of the opening too much. Again, finish with a round of reverse single crochet if desired.
Fit and Customization Tips
One of the great advantages of a modular design like this vest is that it is very easy to customize. If you want a longer vest, simply make your front and back panels taller by adding another row of squares. If you want a boxier silhouette, add another column of squares to the width. If you prefer a cropped look, use just 3 rows of squares instead of 4.
For a more fitted look, you can add ties or a belt made from a simple crochet chain to cinch the vest at the waist. A row of button loops and vintage buttons along one side of the front opening gives a completely different, more structured aesthetic.
You can also play with square size. If you work your squares to 4 inches instead of 5 inches, you will need more squares to cover the same area, but the fabric will feel more refined. If you go up to 6 inches, the construction feels very fast but you have less flexibility in sizing.
Finishing and Care
Once your edging is complete, weave in any remaining ends securely. I always weave each tail in two different directions for extra security, especially for a garment that will be washed and worn regularly.
For blocking the finished vest, gently hand wash it in cool water with a small amount of wool wash or mild soap, roll it in a towel to remove excess moisture, then lay it flat on a blocking mat and ease it into the correct dimensions. Pin the corners if needed. Allow it to dry completely before wearing, which typically takes overnight.
For ongoing care, hand wash this vest each time or use the gentle cycle in a mesh laundry bag. Lay flat to dry. If you have used an acrylic yarn, it may be more machine-washable depending on the specific fiber content, so always check your yarn label.

A Few Words Before You Cast On
Every crocheter I know has a slightly different relationship with granny squares. Some grew up watching a grandmother or aunt work them and feel a deep sense of connection every time they pick up a hook. Others came to them later and discovered the meditative rhythm of working in rounds. Wherever you fall on that spectrum, there is something genuinely special about transforming a pile of small, individual squares into a garment that you will reach for again and again.
This vest is the kind of project that reminds you why you fell in love with crochet in the first place. It is tactile and colorful and deeply satisfying to make. The techniques are accessible enough that you can enjoy the process rather than fighting the pattern, but the finished result looks impressive enough that people will absolutely ask you where you bought it. The best answer, of course, is that you made it yourself.
Take your time with it, enjoy the process of making each individual square, and do not skip the blocking step. A little bit of finishing care at the end will elevate the whole project and make you proud to wear it.
Happy crocheting.
