Make a Granny Square Dumpling Bag — Japanese Knot Bag Free Crochet Pattern Tutorial For Beginners

If you have been looking for a crochet project that is both beginner-friendly and absolutely gorgeous, you have just found it. This free crochet pattern tutorial will walk you through how to make a granny square dumpling bag, also known as a Japanese knot bag, from start to finish. Whether you are brand new to crochet or just looking for a satisfying weekend project, this pattern is approachable, customizable, and results in a bag that looks far more complicated than it actually is. By the end of this tutorial, you will have a beautiful handmade bag with that signature rounded, dumpling-like shape and two looping handles that cross over each other — the classic look of the Japanese knot bag style.

Let’s dive in.

What Is a Japanese Knot Bag?

Before we get into the pattern itself, it helps to understand what makes a Japanese knot bag so special. The Japanese knot bag, sometimes called a kimono bag, is a style of handbag that originated in Japan and is traditionally made from fabric. Its defining feature is the two asymmetrical handles — one long and one short — that loop together through each other when you pick up the bag. This creates a secure, knotted closure without any zipper or button required. The bag essentially holds itself closed.

The shape is also distinctive. Japanese knot bags have a soft, rounded, slightly puffy silhouette that many people describe as looking like a dumpling, which is exactly where the nickname comes from. When you translate this design into crochet — especially using the classic granny square as your foundation — you get something that is simultaneously retro, modern, and completely charming.

The granny square version of this bag adds an extra layer of texture and color play. Granny squares have been a crochet staple for decades, and they are enjoying a major resurgence in popularity right now. Using them as the building blocks for a Japanese knot bag means you can easily customize the colors, mix and match motifs, and create something entirely unique to you.

Supplies You Will Need

One of the best things about this project is that it does not require expensive or hard-to-find materials. Here is what you will need to gather before you begin.

Yarn: Worsted weight yarn works beautifully for this project and is the most forgiving for beginners. You can use a single color for a clean, minimalist look, or pull together several colors from your stash for a colorful, patchwork effect. If you want a sturdier bag that holds its shape well, cotton yarn is an excellent choice. Acrylic yarn works too and tends to be more budget-friendly. For a softer, drapier bag, a cotton-acrylic blend is a lovely middle ground. You will need approximately 200 to 300 yards of yarn total, depending on how large you make your squares and how many you use.

Crochet Hook: A 5mm (H/8) crochet hook is the standard recommendation for worsted weight yarn and will give you a nicely structured fabric that is not too stiff or too loose.

Yarn Needle: You will need a blunt-tipped tapestry needle for weaving in ends and joining your squares.

Scissors: Any sharp pair of scissors will do.

Stitch Markers (optional but helpful): These will help you keep track of your starting points, especially when working in the round.

Blocking Mat and Pins (optional): If you want perfectly uniform squares, blocking them before assembly makes a big difference.

Understanding the Granny Square

If you are a complete beginner, do not worry — the classic granny square is one of the first things most crocheters learn, and for good reason. It is a small, square motif worked in the round from the center outward. It uses only basic stitches: chain stitches, slip stitches, and double crochet clusters. Once you make your first one, you will likely want to make a hundred more.

Here is a quick refresher on the stitches you will use:

Chain stitch (ch): The foundation of almost all crochet. You simply pull loops through loops.

Slip stitch (sl st): A joining stitch used to close rounds and connect motifs.

Double crochet (dc): The main building block of the granny square. You yarn over, insert your hook, pull up a loop, then pull through two loops twice.

If any of these are unfamiliar, spending ten minutes practicing them on a small swatch before starting the pattern will make everything click into place quickly.

Gauge and Sizing

Each finished granny square should measure approximately 4 inches by 4 inches after light blocking. The finished bag will measure approximately 10 to 11 inches wide and 8 to 9 inches tall when assembled. This makes it a perfect everyday bag for carrying your essentials — phone, wallet, keys, a small notebook — without being overly bulky.

If you want a larger bag, simply add a round or two to each granny square, or add more squares to the layout.

Part One: Make the Granny Squares

You will need to make a total of six granny squares for this bag. If you are using multiple colors, this is the time to plan your color scheme. A simple approach is to use one main color (MC) for the center rounds and a contrasting color (CC) for the outer round.

Basic Granny Square Pattern (makes one square):

Start with a magic ring, or chain 4 and join with a slip stitch to form a ring. If the magic ring feels intimidating, the chain-4 method is perfectly fine and slightly easier for beginners.

Round 1: Chain 3 (counts as first dc), work 2 dc into the center of the ring, chain 2. Work 3 dc into the center of the ring, chain 2. Repeat twice more for a total of four clusters of 3 dc, each separated by a chain-2 corner space. Join with a slip stitch to the top of the beginning chain-3. Fasten off if changing colors.

Round 2: Join new yarn in any chain-2 corner space. Chain 3 (counts as first dc), work 2 dc in the same corner space, chain 2, work 3 dc in the same corner space. This creates your first corner. Chain 1. In the next corner space, work 3 dc, chain 2, 3 dc. Chain 1. Repeat around all four corners. Join with a slip stitch to the top of the beginning chain-3. Fasten off if changing colors.

Round 3: Join yarn in any corner space. Chain 3, work 2 dc in the corner space, chain 2, work 3 dc in the same corner space. Chain 1. Work 3 dc in the chain-1 side space. Chain 1. Work the full corner sequence in the next corner space. Continue around, working 3 dc clusters in each side space and full corner sequences in each corner space. Join with a slip stitch. Fasten off and weave in ends.

This three-round square gives you a clean, classic granny square that measures right around 4 inches. Make all six squares before moving on to assembly. If you want to add a fourth round for larger squares and a bigger bag, simply continue the same logic — adding one more cluster to each side and maintaining the corner sequences.

Part Two: Block Your Squares

This step is optional but highly recommended, especially for beginners. Blocking means lightly dampening your squares and pinning them flat on a blocking mat (or a folded towel on a foam board) to dry. This evens out any tension inconsistencies and makes your squares much easier to sew together neatly. Even a simple spray of water and a gentle tug into shape — pinned flat and left to dry overnight — will make your finished bag look more polished.

Part Three: Assembling the Bag

This is where the magic happens. You have your six squares, and now you are going to arrange and join them into the bag shape.

Layout: Think of the bag as a flat pattern before it is assembled. You will arrange three squares in a row for the front panel, and three squares in a row for the back panel. Within each three-square row, the squares sit side by side horizontally.

To join the squares, you can use one of two methods:

Slip stitch join: With right sides facing, hold two squares together and use your crochet hook to slip stitch through both layers along the edge. This creates a slightly raised seam on the inside.

Flat join / whip stitch: Using your yarn needle and a length of yarn, simply whip stitch the edges together from the wrong side. This is often easier for beginners and creates a very flat, invisible seam.

Join the three squares for your front panel into a horizontal row. Repeat for the back panel. You now have two long rectangular panels made of three squares each.

Assembling the body: Place the front and back panels together with wrong sides facing (right sides out). You will now join the bottom edge and the two side edges. Leave the top edge open. The easiest method is to slip stitch or whip stitch around three sides, leaving the top open. You should now have something that looks like a flat, boxy pouch.

Part Four: Making the Handles

The handles are what transform this from a simple pouch into a true Japanese knot bag, and they are surprisingly simple to crochet.

You will make two handles: one that is slightly longer and one that is slightly shorter. This asymmetry is essential to the Japanese knot bag design and is what allows the handles to loop through each other.

Short Handle: Chain 6. Work in rows of single crochet back and forth until the strap measures approximately 12 inches long. Fasten off and leave a tail for sewing.

Long Handle: Chain 6. Work in rows of single crochet back and forth until the strap measures approximately 16 inches long. Fasten off and leave a tail for sewing.

For a slightly more polished handle, you can work in half double crochet instead of single crochet, which gives a little more body and drape. You can also work a single crochet border around the edges of each handle once finished for a neat edge.

Attaching the Handles: This is the step that brings the whole bag together, and the placement matters for getting that signature knot-bag look.

On the front panel, sew the short handle to the left side of the top edge. The handle end should be attached a few inches in from the left corner.

On the back panel, sew the long handle to the right side of the top edge, again a few inches in from the right corner.

When you pick up the finished bag, the short handle threads through the long handle and they loop together, closing the bag in a loose, secure knot. This is exactly how every traditional Japanese knot bag works, just translated into crochet.

Part Five: Finishing Touches

Weave in all remaining ends securely. If you want to line the bag for added structure and to keep small items from slipping through the crochet stitches, cut a piece of fabric to size, fold the edges under, and hand-stitch it inside the bag along the top edge. Cotton quilting fabric works beautifully for this.

You can also add a simple crochet border around the top opening of the bag by joining yarn at any corner and working a round of single crochet all the way around, then finishing with a round of reverse single crochet (also called crab stitch) for a professional, tidy edge.

Tips for Beginners

Tension is one of the biggest challenges when you are new to crochet, and inconsistent tension is perfectly normal. Do not stress if your first square looks a little wonky. By the time you finish the fourth or fifth one, your tension will have evened out considerably. Blocking also corrects a lot of tension variation, which is another reason it is so worth doing.

When joining squares, always use the same yarn weight as your project yarn for the seaming. A contrast color can look lovely as a decorative design choice, but if you want invisible seams, match your yarn as closely as possible.

If you are working with multiple colors and the bag feels like a lot of ends to weave in, try working over your yarn tails as you crochet. This is a technique where you hold the tail of yarn along the edge you are working into and crochet over it, essentially burying it as you go. It significantly reduces the finishing time at the end of the project.

Color Inspiration

One of the absolute best things about this pattern is how wildly customizable it is. Here are a few color combinations to spark your creativity.

For a coastal, summery look, try navy blue, white, and sandy tan. For a retro, vintage-inspired palette, warm orange, mustard yellow, and cream are gorgeous together. For a soft, cottagecore aesthetic, think dusty rose, sage green, and ivory. For a bold, modern statement bag, try black and white squares with a single pop of color on the handles.

You could even do a truly scrappy version using completely different yarn for each of the six squares, using up odds and ends from your stash. The result has a patchwork, maximalist quality that is very on-trend right now and completely unique.

Why This Pattern Is Perfect for Beginners

There are several reasons this granny square dumpling bag is such a great first bag project. First, you are working in small, manageable pieces. Instead of crocheting a large, continuous panel (which can feel overwhelming and leaves a lot of room for mistakes to compound), you are making six small squares. Each one takes about 20 to 30 minutes. If one goes wrong, you have only lost half an hour.

Second, the construction is forgiving. Because the granny square motif has a lot of visual texture and the finished bag has a relaxed, informal shape, small imperfections disappear into the overall design. This is not a project where a slightly uneven edge or an off-center square will be noticeable.

Third, everything you learn here transfers directly to other projects. The granny square is a foundational crochet motif. The joining techniques you practice here are used in blankets, cardigans, pillowcovers, and more. And understanding how to shape and assemble a bag opens up a whole world of functional crochet projects.

Sharing Your Finished Bag

Once you have made your dumpling bag, please do share it! If you post your finished project on Instagram or Pinterest, using the hashtag #grannySquareDumplingBag or #JapaneseKnotBag will help you connect with other crocheters who are making the same pattern.

Final Thoughts

This granny square dumpling bag brings together two things that crochet does best: timeless tradition and playful creativity. The Japanese knot bag shape is elegant and functional. The granny square construction is nostalgic and satisfying. Together, they make a project that is greater than the sum of its parts — a bag you will actually want to carry, made with your own hands, in colors that are completely yours.

Whether you are making this as a gift, a personal accessory, or just a fun way to spend a few evenings, this pattern delivers on every level. Take your time with it, enjoy the process, and do not be afraid to experiment with the colors and sizing. Crochet is wonderfully flexible, and this pattern especially rewards creativity.

Happy crocheting!
