Why Granny Square Skirts Are Having a Major Moment

If you have scrolled through any fashion-forward crochet community recently, you have probably noticed that granny square garments are everywhere. Runways, street style photos, and handmade fashion accounts are all showcasing this classic motif in bold new ways. The granny square skirt, in particular, has become a statement piece for people who love handmade clothing that tells a story.

Part of the appeal is practicality. Granny squares are one of the most beginner-friendly crochet motifs in existence. They work up quickly, they are forgiving when your tension is not perfectly even, and they can be made in any color combination you can dream up. Once you know how to make a basic granny square, you are already most of the way toward making a skirt.

The other part of the appeal is pure aesthetics. An afghan skirt made from joined granny squares has a beautiful patchwork quality to it, a bohemian texture and visual richness that simply cannot be replicated by machine-made fabric. Every skirt ends up unique because every crocheter brings their own tension, color choices, and style to the work.

Materials You Will Need

Before diving into the pattern itself, take a moment to gather everything you need. Having your materials ready before you begin will make the process much smoother.

Yarn: You will want a worsted weight yarn (also sometimes labeled as size 4 or aran weight) for a skirt with good structure and drape. Cotton or a cotton blend is an excellent choice because it has a lovely weight and breathability, which matters a great deal when the skirt is being worn. Acrylic yarn works perfectly well too, especially if you prefer easy care and a wider range of colors. A solid-colored yarn for the border rounds of each square paired with an assortment of coordinating colors for the centers creates the classic granny square aesthetic, but feel free to use all solids, all variegated yarn, or a neutral palette if that suits your taste better. You will need approximately 800 to 1,200 yards of yarn depending on your size and skirt length, with larger sizes and longer skirts requiring more.

Hook: A size 5.0 mm (H/8) crochet hook is a great starting point for worsted weight yarn and produces a fabric with nice drape. If your tension runs tight, go up to a 5.5 mm or 6.0 mm hook. If your tension is very loose, drop down to a 4.5 mm. The goal is a fabric that feels fluid and soft rather than stiff or too open.

Additional supplies: You will need a yarn needle for weaving in ends and joining squares, scissors, stitch markers to keep track of your work, a measuring tape, and approximately one yard of elastic that fits comfortably around your natural waist or wherever you plan to wear the skirt. You may also want a piece of cardboard or blocking mats if you plan to block your squares before assembly.

Understanding Gauge and Sizing

For this pattern, each granny square measures approximately 5 inches by 5 inches after finishing. This is the foundation of the sizing system for the skirt, because the number of squares you make and the way you arrange them determines the final measurements.

To make a skirt that fits a hip measurement of 36 to 38 inches with comfortable ease, you will want to arrange your squares in a grid of 8 squares across and 4 rows tall, which gives you a finished hip measurement of roughly 40 inches with the squares joined. For a smaller hip measurement of 30 to 34 inches, use 6 or 7 squares across. For a larger measurement of 40 to 44 inches or beyond, use 9 or 10 squares across. The beauty of this construction method is that sizing truly is this flexible and this straightforward.

For skirt length, each row of squares adds approximately 5 inches of length. Four rows gives you a midi-length skirt that hits somewhere around the knee or just below it on most people. Add a fifth or sixth row for a maxi skirt. Use only two or three rows for a mini skirt. You control the proportions entirely based on how many squares you make.

Before committing to your full skirt, crochet one sample square and measure it carefully. If your square is coming out smaller than 5 inches, your tension is tight and you should try a larger hook. If it is coming out larger than 5 inches, your tension is loose and you should try a smaller hook. Getting this right before you make 30 or more squares will save you a great deal of frustration later.

The Basic Granny Square Pattern

This is a classic four-round granny square, the foundation of this entire skirt. Once you get comfortable with this sequence, you will find yourself working through squares quickly.

Foundation ring: Make a magic ring, or chain 4 and slip stitch into the first chain to form a ring.

Round 1: Chain 3 (this counts as your first double crochet throughout the pattern), work 2 double crochet into the ring, chain 2, then work 3 double crochet into the ring, chain 2, repeat this sequence two more times so that you have four groups of 3 double crochet separated by chain-2 corner spaces. Slip stitch into the top of the starting chain-3 to close the round. Fasten off if you are changing colors for round 2, or continue if you are working in a single color.

Round 2: Join yarn in any corner chain-2 space. Chain 3, work 2 double crochet in the same space, chain 1, then work a cluster of 3 double crochet into the same corner space, chain 2, then work 3 double crochet into the next corner space, chain 1, then 3 double crochet in the same space, chain 2. Repeat around all four corners. Slip stitch to close. Fasten off or continue.

Round 3: Join yarn in any corner chain-2 space. Chain 3, work 2 double crochet in the same space, chain 1, then 3 double crochet in the chain-1 side space, chain 1, then work the corner cluster of 3 double crochet, chain 2, 3 double crochet in the same corner. Continue around, working 3 double crochet in each chain-1 space along the sides and the full corner cluster at each corner. Slip stitch to close.

Round 4: This is your border round, worked in your main or coordinating color. Join yarn in any corner space. Chain 3, work 2 double crochet in the corner, chain 1, then 3 double crochet in each chain-1 side space along the edge, working chain 1 between each cluster and the full corner treatment at each of the four corners. Slip stitch to close. Fasten off and weave in all ends.

Your finished square should be a neat, slightly rounded square with defined corners and a satisfying weight to it. The chain-1 spaces between clusters along the sides and the chain-2 spaces at the corners create a consistent joining structure you will use when assembling the skirt.

Color Planning Your Skirt

One of the most enjoyable parts of this project is planning your colors. There are several approaches that work beautifully.

A scrappy, rainbow approach uses a different combination of colors in every single square, working through your yarn stash without worrying too much about matching. The result looks eclectic and joyful, held together visually by a single consistent border color used on round 4 of every square. Black, white, cream, and tan all make excellent unifying border colors.

A gradient approach arranges your squares so colors shift gradually from one side of the skirt to the other, or from top to bottom, moving through a spectrum. This requires more planning upfront but produces a breathtaking finished result.

A tonal approach uses two or three closely related colors, working variations of the same hue throughout for a sophisticated, understated look. Shades of dusty blue, sage green, or terracotta with cream accents create a palette that feels both modern and timeless.

A high-contrast graphic approach uses just two colors, alternating them in a checkerboard arrangement for bold visual impact. Navy and white, black and cream, or red and ivory all create striking results with minimal complexity.

Whatever approach you choose, lay your squares out before joining them to see how the arrangement looks. Take a photo so you have a reference as you work through the assembly.

Joining Your Squares

There are two popular methods for joining granny squares, and both work beautifully with this skirt pattern. The method you choose affects both the look of the finished fabric and the feel of it against your skin.

The flat slip stitch join is worked with the wrong sides of two squares held together, inserting your hook through the corresponding chain spaces of both squares and working a slip stitch join along the edge. This creates a nearly invisible seam on the right side with a very slight ridge on the wrong side. It produces a flat, flexible fabric and is an excellent choice for garments.

The flat single crochet join is similar but uses single crochet instead of slip stitch. This creates a more visible seam line on the right side that reads almost like a decorative element, a neat ridge of stitches that emphasizes the grid structure of the skirt. Many crocheters prefer this join because it adds a visual element that feels intentional rather than hidden.

Begin by joining your squares into horizontal rows first, then join the rows to each other. Keep track of which end of each row will become the top of the skirt and which end will become the hem.

When you have joined all your squares into the full rectangle of fabric, you will fold it into a tube and join the two short ends together to form the body of the skirt. Make sure your colors line up the way you planned before making this final seam.

Adding the Waistband

The waistband finishes the skirt and creates the channel for your elastic. There are a few ways to approach this depending on the look you want.

For a simple gathered waistband, work several rounds of single crochet around the top edge of the skirt, keeping your tension consistent. After four or five rounds, fold the crochet band to the inside of the skirt and use your yarn needle to whipstitch it down, leaving a small opening to thread your elastic through. Cut your elastic to your waist measurement plus about half an inch for overlap, thread it through the channel, sew the ends together securely, and close the opening.

For a more decorative waistband, work a few rounds in a contrasting color or add a shell stitch edging at the very top before folding it over. This adds a little extra visual interest at the waistline.

You can also skip the elastic entirely and add ties or a drawstring for a more relaxed, adjustable fit. This works particularly well if the skirt will sometimes be worn as a beach coverup or layered over other garments.

Finishing the Hem

The hem of the skirt is the bottom edge, which is already naturally finished by the outer rounds of your granny squares. However, a few options can elevate the look further.

Working a simple round of single crochet or slip stitch in your main border color unifies the hem and gives it a clean, intentional edge. A row of shell stitch or fan stitch creates a flirty, slightly wavy hem that adds movement to the skirt. A picot edging, where you chain 3 and slip stitch into the first chain to form a small loop, worked along the hem adds delicate texture without adding significant length.

Try the skirt on at this stage and check the length before adding any hem treatment. If you want it a bit longer, you can add one or more rounds of double crochet or a partial row of shells to build up the hem edge before adding your decorative finish.

Styling Your Granny Square Afghan Skirt

Now comes the truly fun part: wearing your creation. The granny square afghan skirt is one of the most versatile garments in a handmade wardrobe, and it pairs beautifully with a surprising range of tops and accessories.

For a casual boho look, pair the skirt with a simple fitted tank top or a cropped t-shirt tucked in at the front. Flat sandals or espadrilles complete the summer-ready outfit. This is the kind of effortless combination that photographs beautifully and is genuinely comfortable to wear all day.

For an evening look, pair the skirt with a silky camisole or a fitted long-sleeve top in one of the colors pulled from your skirt. Block-heeled sandals or ankle boots add polish, and the combination feels elevated without being overdressed.

Layered over a pair of wide-leg trousers or linen pants, the skirt takes on an avant-garde quality that feels fashion-forward and unexpected. This works especially well with a neutral, tonal skirt over contrasting trousers.

In cooler weather, wear the skirt over opaque tights or even casual trousers, paired with a cozy oversized sweater or a structured blazer. The contrast between the tailored top and the handmade textured skirt creates an interesting, intentional look that highlights the artistry of your work.

Tips for Success

A few final pieces of advice will help your project come together beautifully. Weave in your ends as you go rather than saving them all for the end, because a skirt with 30 or more squares produces a significant number of yarn tails and the task can feel overwhelming if left until assembly time.

Block your squares before joining if possible. Pinning them to their correct dimensions while damp and allowing them to dry completely will make the joining process much easier and give you a more polished, even finished fabric.

Count your stitches at the end of each round as you work your squares. A missed chain or an extra cluster can throw off the shape of the square in ways that become very apparent during assembly.

Finally, trust the process. Granny squares are wonderfully forgiving, and small variations in your tension or color placement are part of what makes a handmade garment beautiful. No two crocheted skirts will ever look exactly alike, and that is precisely the point.

Your granny square afghan skirt is a wearable expression of your creativity, your color sense, and the hours of satisfying work you put into every single square. Wear it proudly, and do not be surprised when people stop you to ask where it came from.
