Japanese Knot Bag Knitting Pattern: A Complete Guide to Making This Elegant Accessory
There is something deeply satisfying about a bag that looks more complicated than it actually is. The Japanese knot bag is exactly that kind of project — a stunning, asymmetrical tote that draws admiring glances and inevitably prompts the question, “Where did you get that?” When you can answer, “I made it myself,” the pride you feel is entirely warranted. This guide walks you through everything you need to know about knitting your own Japanese knot bag, from understanding the design’s origins to casting on your first stitch and finishing with a beautiful, polished result.
Whether you are a seasoned knitter looking for your next interesting project or an intermediate crafter ready to push your skills, this Japanese knot bag knitting pattern is approachable, endlessly customizable, and genuinely rewarding to complete.
What Is a Japanese Knot Bag?
The Japanese knot bag — sometimes called an obi knot bag or azuma bukuro — has its roots in traditional Japanese textile culture. The original version was a simple cloth square folded and stitched in a particular way to create a bag with two looping handles of different lengths. To close the bag, you simply loop the shorter handle through the longer one and pull snug, creating that distinctive knotted silhouette.
Knitters and crocheters have embraced this design enthusiastically because it translates beautifully into knitted fabric. A knitted Japanese knot bag has a soft, draped quality that cloth versions sometimes lack, and the texture of hand-knitted yarn adds a richness that elevates the bag from a simple accessory to something that feels handcrafted in the best possible sense.
What makes this project particularly interesting from a construction standpoint is that it is worked in a largely geometric way. You knit two rectangular or slightly shaped panels, seam them together along specific edges, and the three-dimensional bag shape emerges almost like magic from the flat fabric. Understanding the geometry before you begin makes the whole process feel intuitive rather than mysterious.
Materials You Will Need
Before diving into the pattern, let’s talk about what you will need to gather. Getting your materials right makes a significant difference in the final outcome.
Yarn: The ideal yarn for a Japanese knot bag is one with some body and structure — something that will hold its shape when the bag is in use but still drapes elegantly. A worsted weight cotton or cotton-blend yarn works beautifully for a practical everyday bag. If you want something lighter and more decorative, a DK weight linen or linen-blend gives a lovely drape with enough structure to keep the bag from going completely limp. For a more luxurious feel, a silk-blend or bamboo yarn creates a gorgeous sheen. Plan on approximately 250 to 350 yards for a medium-sized bag, depending on your gauge and the exact dimensions you choose.
Needles: For worsted weight yarn, a US size 7 (4.5mm) needle works well. For DK weight, try a US size 5 (3.75mm). You want a fabric that is slightly tighter than what you might use for a garment — you do not want so much drape that the bag loses its structure, but you also do not want it so stiff that it feels uncomfortable to carry. Circular needles work fine, especially if you prefer them, though straight needles are perfectly adequate since this pattern is worked flat in pieces.
Notions: You will need a tapestry needle for seaming, scissors, and stitch markers if you like to mark your progress. A row counter is helpful but not essential.
Gauge: Aim for approximately 18 to 20 stitches and 24 to 26 rows over 4 inches in stockinette stitch using worsted weight yarn. Always knit a gauge swatch before beginning, especially for this project. Because the bag relies on geometric proportions, being off on your gauge will affect the finished dimensions and the way the handles loop together.
Understanding the Construction
The Japanese knot bag is made from two separate rectangular panels. Let’s call them Panel A and Panel B.
Panel A is the main body panel. It is longer and wider, and one end of it becomes the long handle.
Panel B is the secondary panel. It is slightly shorter, and one end becomes the short handle.
When both panels are complete, you seam them together along specific edges to form the bag body, leaving the handles free. The seaming is where the bag’s clever geometry comes to life, so it is worth taking a moment to understand it before you start rather than trying to puzzle it out at the end.
Think of each panel as a rectangle divided into three sections: the handle portion at one end, the main bag body in the middle, and a flap portion at the other end. When you seam the two panels together, the flap of Panel A is seamed to one side of Panel B’s body, and the flap of Panel B is seamed to one side of Panel A’s body. The handles are left unseamed and free.
The Pattern
The following pattern creates a bag with finished dimensions of approximately 11 inches wide by 9 inches tall (when the bag is closed), with a long handle of about 14 inches and a short handle of about 9 inches. These are lovely proportions for a market bag or a casual everyday tote.
Panel A
Cast on 48 stitches.
Work in your chosen stitch pattern for the entire panel. This pattern is written in stockinette stitch, but seed stitch, garter stitch, or any simple textured stitch will work beautifully and adds visual interest.
Row 1 (RS): Knit to end.
Row 2 (WS): Purl to end.
Repeat rows 1 and 2 until the panel measures 36 inches from the cast-on edge.
Bind off all stitches.
Panel B
Cast on 48 stitches.
Work exactly as Panel A until the panel measures 28 inches from the cast-on edge.
Bind off all stitches.
Stitch Pattern Variations
If you would like to add texture, here are a few options that work particularly well for this bag.
Seed Stitch: Cast on an even number of stitches. Every row: K1, P1; repeat from to end. This creates a reversible, slightly firmer fabric that adds nice body to the bag.
Basketweave: Cast on a multiple of 8 stitches plus 4. Work as follows:
Rows 1 and 3 (RS): K4, P4; repeat from to last 4 stitches, K4.
Rows 2 and 4 (WS): P4, K4; repeat from to last 4 stitches, P4.
Rows 5 and 7 (RS): P4, K4; repeat from to last 4 stitches, P4.
Rows 6 and 8 (WS): K4, P4; repeat from to last 4 stitches, K4.
Repeat rows 1 through 8.
This creates a classic woven-looking texture that suits the Japanese aesthetic of the bag particularly well.
Simple Rib: Cast on a multiple of 4 stitches. Every row: K2, P2; repeat from to end. A rib pattern gives the bag slight horizontal elasticity and a lovely tailored look.
Seaming the Bag
This is the step that intimidates people the most, but once you understand the logic, it is genuinely straightforward. Take your two finished panels and lay them flat.
Fold Panel A in half lengthwise to find the center point — this is the bottom of your bag. Mark this point with a stitch marker or a piece of contrast yarn. Now measure 9 inches up from this center point in each direction. Mark those two points. The section between those two markers is the body of your bag — approximately 18 inches of the panel. The remaining length on either end becomes the handles.
Do the same for Panel B. Fold it, find the center, and mark 9 inches up from center on each side.
Now lay Panel B on top of Panel A with right sides facing each other. You are going to seam one short end of Panel B to one long side of Panel A’s body section. To be specific: take the bottom short edge of Panel B (the cast-on or bind-off edge at the short handle end) and align it with one long edge of Panel A’s body section. Seam these edges together using mattress stitch or whipstitch, working neatly and consistently.
Next, take the bottom short edge of Panel A (the short handle end) and seam it to one long edge of Panel B’s body section.
When you turn the bag right side out, you will see that the two panels have formed a pouch. The handles extend naturally from the top, and the bag’s body has a satisfying three-dimensional shape. The long handle loops through the short handle to close the bag.
If this sounds confusing in the reading, try laying out two pieces of paper the appropriate proportions and folding and taping them — the physical model will make the seaming logic immediately clear.
Finishing Touches
After seaming, weave in all your ends thoroughly. Because this bag will be picked up, put down, and generally used in daily life, you want those ends secure.
Blocking: Wet blocking transforms a knitted bag. Soak your finished bag in cool water for about 20 minutes, gently squeeze out the excess water without wringing, and lay it flat on a towel or blocking mat. Shape it to your desired dimensions, pinning if needed, and let it dry completely. Blocking evens out stitches, opens up textured patterns, and gives the bag a polished, professional look.
Lining: Adding a fabric lining is optional but practical. A simple cotton lining prevents small items from poking through the knitted fabric and helps the bag hold its shape. Cut two pieces of fabric to match your panel dimensions, seam them together in the same configuration, leave the top open, fold the raw edges under, and slip stitch the lining inside the finished bag.
Embellishments: This is where you can really make the bag your own. A line of contrasting color along the handles, a simple embroidered motif on one of the panels, a decorative button near the knot point, or even beads woven into the fabric during knitting — all of these can add personality without overwhelming the clean, elegant lines of the design.
Yarn Recommendations and Color Ideas
The color and fiber you choose will entirely change the character of this bag. A crisp white cotton creates something that feels fresh and summery. A deep indigo linen reads as sophisticated and slightly bohemian. A jewel-toned merino wool feels cozy and luxurious. Variegated or hand-dyed yarn can be absolutely stunning — because the bag is worked in a simple rectangular shape, the yarn can pool and stripe in ways that become part of the design.
For beginners to this pattern, a solid or semi-solid color is easier to work with because it makes the seaming much easier to see. Once you are familiar with the construction, gradient yarns or bold colorwork can take the bag to a completely different level.
If you want to try colorwork, a simple two-color stripe is very effective. Work stripes of equal width in two colors for a graphic, modern look, or work wide stripes in one color with narrow accent stripes in a contrasting one.
Sizing Adjustments
The beauty of this pattern is how easy it is to scale. To make a smaller bag — perhaps a coin purse or a small clutch — simply cast on fewer stitches and reduce the length of both panels proportionally. A miniature version with 24 stitches and panels of 18 and 14 inches respectively makes an adorable little pouch.
For a larger market bag or beach tote, cast on more stitches and lengthen the panels. If you go significantly larger, consider a yarn with more structure — a chunky cotton or a linen-cotton blend — to ensure the bag can actually carry weight without stretching out of shape.
Keep in mind that the ratio of Panel A to Panel B should remain consistent regardless of size. Panel A should be approximately 1.25 to 1.3 times longer than Panel B to create handles of the right relative length.
Troubleshooting Common Issues
The handles are too stiff or too floppy. If the handles feel stiff and unwieldy, try going up a needle size on your next version. If they feel too floppy to hold their shape, go down a needle size or choose a yarn with more body.
The bag loses its shape when filled. This is usually a yarn or gauge issue. A slightly firmer gauge helps enormously. You can also add a fabric base insert — a piece of heavy interfacing or a bag base cut to size — to give the bottom more structure.
The seaming looks uneven. Mattress stitch can be tricky on the first attempt. Practice on a small swatch first, and make sure you are always picking up the same number of bars or stitches on each side. Working with good light and a blunt tapestry needle makes a significant difference.
The knot won’t stay closed. This is usually a proportion issue. Make sure the short handle is genuinely shorter than the long handle, and that the body section is wide enough for the handle to loop through comfortably. Blocking the bag after finishing often helps the handles develop the right amount of flexibility and drape to knot neatly.
Why Knitters Love This Project
Beyond the practical and aesthetic appeal, there are specific qualities about this project that knitters return to again and again. The construction is logical and satisfying. You finish each panel knowing it is a complete, measurable piece of work, and then the seaming is almost like solving a puzzle. The finished bag has a quality of clever simplicity — it looks elaborate but is ultimately the result of a few rectangles and some thoughtful seaming.
The project is also highly portable. Both panels are worked flat with no shaping, no increases, no decreases, and no complex stitch counts to track. You can pick this up in the middle of a round panel and put it down again without losing your place. It is the kind of project you can work on while watching television, or carry in your own (current) bag for work on your commute.
And there is something particularly pleasing about making a bag with knitting needles and yarn — creating one useful object from another. The finished Japanese knot bag becomes a companion for daily life, something you made with your own hands that shows up in photographs, travels with you, holds your groceries or library books or beach towel, and quietly carries all that craft and care in its seams.
A Final Note on Making This Pattern Your Own
Patterns are starting points. This one gives you a solid foundation and reliable proportions, but the most interesting finished bags will come from the choices you make — the yarn you fall in love with, the stitch pattern you want to explore, the color combination that has been living in your head. There are knitters who have made versions of this bag in every yarn weight from fingering to bulky, in every color from natural undyed wool to vivid hand-painted silk. Each one is a different object with a different personality.
Take the pattern, understand the geometry, and then trust your instincts. That is really the spirit of this kind of project, and it is very much in keeping with the tradition of craft that the Japanese knot bag comes from — functional beauty made with care, adapted and remade with each new pair of hands.
Cast on, and enjoy every stitch.
