How To Sew Knitting Project Bags The Easy Way

If you’ve ever found yourself wrestling with yarn that’s tumbling out of a grocery bag, tangling around your feet, or picking up lint from the bottom of your purse, you already know why a dedicated knitting project bag is worth every minute it takes to make. These handy little pouches keep your work-in-progress clean, organized, and portable — and the best part is that sewing your own is genuinely one of the most satisfying beginner-to-intermediate projects you can tackle at a sewing machine.

This guide will walk you through everything you need to know about how to sew knitting project bags the easy way. Whether you want a simple drawstring pouch, a zippered tote, or a lined bag with pockets, you’ll find clear instructions here. By the end, you’ll have a beautiful, functional bag you made yourself — and probably enough enthusiasm to make a dozen more as gifts.

Why Make Your Own Knitting Project Bag?

Before we get into the how-to, let’s talk about why handmade beats store-bought every single time when it comes to project bags.

First, customization. You can choose the exact dimensions you need. A shawl in progress requires a much larger bag than a pair of socks, and when you sew your own bag you’re not stuck with whatever size happens to be on the shelf. Second, fabric choice matters more than people realize. Knitters often prefer tightly woven cotton or canvas because yarn doesn’t snag on it the way it can on loosely woven fabrics. When you make your own bag, you control every detail. Third, it’s genuinely economical. A yard or two of quilting cotton costs a few dollars and can yield multiple bags, while nice project bags in yarn shops can run anywhere from $20 to $60.

And finally, there’s the pure joy of using something you made. Pulling out a handmade bag at a knit night or in a waiting room is quietly satisfying in a way that’s hard to describe but very easy to feel.

Tools and Materials You’ll Need

Getting organized before you sit down at the machine saves a lot of back-and-forth. Here’s what to gather.

For the basic drawstring bag, you’ll need about half a yard of exterior fabric (quilting cotton, canvas, or linen all work beautifully), half a yard of lining fabric if you want it lined, a yard and a half of cord or ribbon for the drawstring, a large safety pin or bodkin for threading, your sewing machine, coordinating thread, scissors or a rotary cutter, a cutting mat and ruler, and an iron.

For the zippered project tote, the list expands slightly: you’ll add a zipper (12 to 14 inches works for most project bags), zipper foot for your sewing machine, and a small piece of interfacing if your outer fabric is on the lighter side.

Optional but recommended tools include wonder clips or sewing clips (especially helpful when working with canvas), a water-soluble fabric pen for marking, and pins. If you’re new to zippers, pick up a few extra in case you want to practice.

Choosing the Right Fabric

Fabric choice is one of those things that seems minor but actually makes a significant difference in how your finished bag looks, feels, and functions.

Quilting cotton is probably the most popular choice for project bags. It’s widely available, comes in thousands of prints, is easy to sew, and has a tight enough weave that yarn doesn’t catch on it. Look for 100% cotton rather than cotton blends if you can, as blends can sometimes pill over time.

Canvas and denim are excellent for the outer layer when you want a sturdier bag. They hold their shape well and develop a nice worn-in quality over time. Keep in mind they’re thicker and may require a heavier needle (a size 90/14 or 100/16 jeans needle works well for denim).

Linen has a lovely texture and is very popular in the knitting community for its natural, earthy aesthetic. It does fray more than cotton, so finish your seam allowances carefully.

For lining fabric, a smooth, slippery cotton or even a lightweight cotton muslin is ideal. You want the lining to allow yarn to glide in and out easily without snagging.

Avoid stretchy fabrics, loosely woven materials, and anything with a heavy texture or pile. These can cause problems both during sewing and during use.

How To Sew a Simple Drawstring Knitting Project Bag

This is the easiest version and a perfect starting point. It comes together in under an hour once you’ve cut your pieces.

Step 1: Cut Your Fabric

Cut two rectangles of your outer fabric measuring 14 inches wide by 16 inches tall. Cut the same two rectangles from your lining fabric. If you’re making an unlined bag, you only need the two outer pieces.

Step 2: Create the Drawstring Channel

On one of the outer fabric pieces, fold down the top edge by half an inch toward the wrong side and press with an iron. Fold down another inch and press again. Pin or clip in place. Sew along the bottom edge of this fold, keeping your stitching about an eighth of an inch from the fold’s lower edge. This creates the casing through which your drawstring will thread. Repeat on the second outer fabric piece. If you’re making a lined bag, do the same on both lining pieces.

Step 3: Sew the Bag Body

Place your two outer fabric pieces right sides together, aligning all edges. Sew down both side seams and along the bottom using a half-inch seam allowance. Leave the top open. Backstitch at the beginning and end of each seam. Clip the corners diagonally to reduce bulk, being careful not to cut through your stitching. Turn right side out and press.

Repeat with the lining pieces, but this time leave a 3 to 4 inch gap in the bottom seam. This gap is how you’ll turn the bag right side out later. Do not turn the lining right side out — leave it wrong side out.

Step 4: Join the Outer Bag and Lining

Slide the outer bag (right side out) inside the lining (wrong side out) so that the right sides are facing each other. The drawstring channels should be at the top. Align the top edges and pin or clip all the way around. Sew along the top edge using a half-inch seam allowance.

Reach through the gap in the lining’s bottom seam and pull everything right side out. Poke out the corners gently with a blunt tool. Tuck the lining inside the outer bag, press the top edge well, and topstitch around the top to give it a clean, finished look. Stitch the gap in the lining closed by hand or machine.

Step 5: Thread the Drawstring

Attach a large safety pin to one end of your cord and thread it through the casing on the front, all the way around, and back out the same opening. Then take a second piece of cord, start it from the other opening on the back, thread it all the way around, and bring it back out that same opening. Tie the ends of each cord together in a knot. Pull both cords to close — you now have a classic two-cord drawstring bag that closes from both sides.

How To Sew a Zippered Knitting Project Bag

Zippers feel intimidating, but they’re genuinely one of the best closures for project bags because they keep your work secure even inside a larger tote. This method is sometimes called the “burrito” method, and once you’ve done it once you’ll want to put zippers on everything.

Step 1: Cut Your Pieces

Cut one rectangle of outer fabric at 13 inches wide by 15 inches tall. Cut the same from your lining fabric. This makes a medium-sized project bag. Scale up or down based on your needs.

Step 2: Prepare Your Zipper

If your zipper is longer than your bag is wide, you can shorten it. Simply sew a few times across the zipper tape at the length you need, creating a new stop, then trim the excess leaving about half an inch of tape below your new stop.

Step 3: Attach the Zipper to the Outer Fabric

Place your outer fabric rectangle right side up. Lay the zipper face down along the top edge, with the zipper pull at one side. Place the lining fabric right side down on top of the zipper, sandwiching the zipper between the two fabrics. All three layers should be aligned along the top edge. Using your zipper foot, sew along this top edge. Flip the outer fabric and lining away from each other and press. Topstitch along this seam close to the zipper.

Step 4: Attach the Other Side of the Zipper

Bring the other short edge of your outer fabric up to the other side of the zipper and repeat: outer fabric right side up, zipper face down, lining face down on top. Sew, flip, and press. You should now have a tube-like shape with the zipper running along one edge. Topstitch the second side as well.

Step 5: Sew the Side Seams

This is the burrito step. Open your zipper partway — this is essential, as it gives you a way to turn the bag right side out. Arrange the bag so the outer fabric pieces are right sides together and the lining pieces are right sides together (you’re essentially folding it so the outer fabric is nested inside the lining, like rolling a burrito). The zipper will be at one end of this arrangement. Pin the side seams, leaving a gap of about 4 inches in the lining seam for turning. Sew down both side seams.

Reach through the opening in the lining and pull the entire bag right side out through the gap. Push out the corners, press everything flat, and stitch the lining gap closed. Tuck the lining inside the bag. Press once more and admire your work.

Adding a Pocket to Your Project Bag

Internal pockets are a game-changer for storing stitch markers, tapestry needles, row counters, and all the small tools that otherwise rattle around at the bottom of your bag. Adding one is easier than you might expect.

Before you assemble your bag, cut a rectangle of lining fabric about 6 inches wide by 5 inches tall. Fold the top edge over by half an inch twice and stitch it down to create a clean hem. Place this pocket piece on the right side of one of your lining panels, aligning the raw edges along the sides and bottom. Stitch around three sides, leaving the hemmed top open. You can even stitch a vertical line down the center of the pocket to divide it into two smaller sections — perfect for keeping your scissors separate from your markers.

Tips for Sewing Better Project Bags Every Time

A few habits will make a noticeable difference in your results, whether you’re on your first bag or your fifteenth.

Press as you go. Ironing each seam before you sew the next one is one of the single most effective things you can do to improve the look of your finished project. It takes an extra minute but the difference is real.

Use the right needle for your fabric. A fresh universal needle (size 80/12) works for most quilting cottons. For canvas or denim, go up to a 90/14 or 100/16. A dull or wrong-size needle is responsible for more skipped stitches and puckered seams than almost any other factor.

Clip your corners and grade your seams. Cutting diagonally across the corner of a seam before turning removes bulk and gives you clean, sharp corners. On thicker fabrics, you can also trim one seam allowance slightly shorter than the other (called grading) to reduce bulk in the seam.

Backstitch consistently. Always backstitch at the beginning and end of every seam. This takes about two seconds and prevents your seams from unraveling.

Test your zipper before you close the bag up. This sounds obvious, but it’s easy to forget in the excitement of finishing, and there’s nothing more frustrating than completing a bag only to discover the zipper is in backward.

Sizing Guide for Different Knitting Projects

One of the great advantages of making your own bags is sizing them exactly to what you’re working on. Here are some general dimensions to keep in mind.

For socks and small accessories, a bag around 10 inches wide by 12 inches tall is usually sufficient and keeps things compact. For shawls and larger accessories, aim for 14 to 16 inches wide by 16 to 18 inches tall. For sweater projects, you may want to go even larger — 18 by 20 inches or more — especially if you’re keeping multiple balls of yarn together. For WIP (work-in-progress) bags meant to hold an entire project over a long period, a tote-style bag with an open top or a wide zipper tends to work better than a drawstring, since you’ll be opening and closing it frequently.

Fabric Yardage and Project Planning

For most medium-sized project bags, half a yard of outer fabric and half a yard of lining fabric is enough to cut multiple bags if you plan efficiently. For larger tote-style bags, budget a full yard of each. When shopping fabric online or in a store, don’t forget to account for pre-washing. All cotton and linen should be washed before cutting to account for any shrinkage. Run it through a warm wash and dry cycle, then press it smooth before you cut.

Gifting Handmade Project Bags

Knitting project bags are one of the most appreciated handmade gifts you can give to a crafter. They’re personal, practical, and endlessly customizable. If you’re making bags as gifts, consider asking about the person’s favorite colors or picking a fabric that reflects their personality. You can also stuff the bag before gifting it — a skein of nice yarn, a set of stitch markers, and a pair of small scissors tucked inside makes an incredibly thoughtful present.

For gifting, the zippered version tends to be more impressive and practical than the drawstring, though both are genuinely useful. A set of two bags in coordinating fabrics — one for the main project and one for notions — is a gift any knitter would treasure.

Final Thoughts

Learning how to sew knitting project bags the easy way is one of those skills that keeps on giving. Once you’ve made your first one, you’ll start seeing the potential for more in every fabric you encounter. The techniques covered here — simple drawstring construction, the zippered burrito method, adding interior pockets — give you a toolkit you can mix and match endlessly depending on what you need.

Start with the drawstring bag if you’re new to sewing. It’s forgiving, fast, and genuinely useful from the first stitch. When you’re ready to level up, tackle the zippered version and discover how satisfying it is to pull a smooth, beautiful zipper across the top of something you built yourself. Add a pocket the next time around. Try a different fabric. Scale the size up or down.

The best project bag is the one that fits your life, and when you make it yourself, it always will.
