Scrap Yarn Crochet Purse – Zero Waste Bag Pattern

There is something deeply satisfying about transforming a jumbled basket of leftover yarn into something beautiful and functional. If you have ever finished a large crochet project and found yourself staring at a pile of odds and ends — bits of worsted weight, a partial skein of cotton, some chunky remnants from last winter’s hat — this pattern was written for you. This scrap yarn crochet purse is a zero waste bag pattern that celebrates every colorful leftover, turning what might otherwise gather dust into a sturdy, stylish bag you will actually carry.

This post will walk you through everything: the supplies you need, how to think about color and texture when working with scraps, the full written pattern, finishing tips, and ideas for making this bag completely your own. Whether you are a beginner looking for a forgiving first bag project or an experienced crocheter who wants a mindful, sustainable make, this purse has something for you.

Why Scrap Yarn Crochet Is Worth Embracing

Before we get into the how-to, let’s talk about why scrap yarn crochet is having such a deserved moment in the crafting world. The yarn industry, like most textile industries, generates a surprising amount of waste. As individual crafters, we cannot fix that at scale — but we can be intentional about how we use what we already have.

Using up scrap yarn means fewer partial skeins headed to donation bins or landfills. It means you are not spending money on new materials for every project. And honestly, it means some of the most interesting, one-of-a-kind finished objects you will ever make. No two scrap yarn bags will look alike. The color combinations that come out of using what you have on hand are often bolder and more unexpected than anything you would have deliberately chosen from a palette.

There is also something freeing about a low-stakes project. When you are using scraps, the pressure is off. You are not protecting an investment of expensive yarn. You can try new stitches, experiment with color sequences, and make decisions on the fly. If something does not work, you rip it back and try again — and you have lost nothing but a few minutes.

What Yarn Works Best for This Pattern

This pattern is designed to be flexible, but there are a few guidelines that will help your finished bag hold its shape and look cohesive.

The most important thing is to work within a similar weight range throughout the bag. Mixing a chunky yarn with a fingering weight yarn in the same row creates uneven tension and a bag that looks more accidental than intentional. The pattern works best with worsted weight (size 4) scraps, but you can absolutely make it work with bulky (size 5) or DK weight (size 3) scraps if you adjust your hook size accordingly and stick to one weight throughout.

Fiber content matters for structure. Cotton and cotton-blend yarns make a sturdy bag that holds its shape, which is ideal for purse construction. Acrylic is widely available as a scrap yarn and works well here too, especially if you line the bag. Wool and wool blends will also work, though the bag will have a softer, more slouchy drape. Avoid very stretchy or slippery fibers like bamboo or silk for the main body of the bag — they tend to make a bottom-heavy purse that loses its structure over time.

Do not stress about dye lots. That is the entire point of scrap yarn work. The color changes are the design.

Supplies You Will Need

To make this scrap yarn crochet purse, gather the following materials before you begin.

Yarn: Approximately 200–250 yards of worsted weight yarn (size 4) total, in as many colors and textures as you like. Each color section uses anywhere from 10 to 30 yards, so you can use very small remnants throughout.

Hook: US size J/6.00mm crochet hook, or the size that gives you a firm, structured fabric at your chosen yarn weight. A looser gauge makes a floppier bag, so err on the side of going down a hook size if your swatch feels soft.

Lining fabric (optional but recommended): A quarter yard of cotton fabric for the interior lining. Canvas or quilting cotton both work well.

Bag handles: A pair of purse handles in wood, bamboo, or plastic, available at most craft stores or online. The ones used here measure approximately 6 inches wide. Alternatively, you can make a crochet strap or use ribbon.

Notions: Yarn needle for weaving in ends, scissors, stitch markers, sewing needle and thread if you are adding a fabric lining.

Gauge and Finished Size

Gauge: 14 stitches and 16 rows = 4 inches in single crochet with a size J hook and worsted weight yarn.

Gauge matters more for bag projects than you might think. A tighter gauge means a stiffer, more structured bag that holds its shape. A looser gauge gives you a drapey, slouchy result. Neither is wrong — they just produce different bags. For a purse that holds its shape when set down, aim for the tighter end of the range.

Finished dimensions: Approximately 11 inches wide by 9 inches tall (before the handle attachment), with a base of approximately 11 by 3 inches. This is a medium-sized everyday purse — big enough for your phone, wallet, keys, and a few extras, without being overwhelming to carry.

Pattern Notes

This bag is worked in two flat panels that are then seamed together at the sides and bottom, with a flat base rectangle worked separately and attached. The color changes happen organically as you run out of one yarn color and join the next — there is no prescribed stripe sequence, and that is by design.

The stitch pattern alternates rows of single crochet and half double crochet to create a subtle texture that adds visual interest without requiring any specialty stitches. This keeps the pattern accessible to crocheters at an intermediate beginner level and above.

Turning chains are not counted as stitches in this pattern. Chain 1 to turn for single crochet rows, chain 2 to turn for half double crochet rows.

To change colors cleanly, work the last stitch of the old color until two loops remain on the hook, then pull the new color through those two loops to complete the stitch. Leave a 6-inch tail on both the old and new yarn for weaving in later.

The Pattern

Base Rectangle

Using your first color, chain 15.

Row 1: Single crochet in the second chain from the hook and in each chain across. (14 stitches) Chain 1, turn.

Row 2: Single crochet across. Chain 1, turn.

Repeat Row 2 until the piece measures 11 inches long. Fasten off, leaving a long tail for seaming.

This rectangle will form the bottom of your bag and gives it its flat, stable base. If you want a wider or narrower base, adjust the starting chain in increments of 2.

Front Panel

Using your first scrap color, chain 39.

Foundation Row: Single crochet in the second chain from the hook and in each chain across. (38 stitches) Chain 1, turn.

Row 1 (and all odd-numbered rows): Single crochet across. Chain 1, turn.

Row 2 (and all even-numbered rows): Half double crochet across. Chain 2, turn.

Continue alternating these two rows, changing colors as your scraps run out or whenever you feel like a color change. There is no wrong answer here. Work until the panel measures approximately 9 inches from the foundation row.

Last row: Single crochet across. Do not fasten off.

Handle Attachment Row: Chain 1, turn. Single crochet across the first 10 stitches. Chain 10, skip 18 stitches (this creates the opening through which the purse handle will be inserted), single crochet across the remaining 10 stitches. Chain 1, turn.

Next Row: Single crochet across all stitches, working 10 single crochets into the chain-10 space to close it up. (38 stitches)

Work 2 more rows of single crochet. Fasten off and weave in ends.

Back Panel

Work the back panel exactly as the front panel, changing colors in whatever sequence you like. The front and back do not need to match — in fact, contrasting panels are part of the charm of this zero waste design.

Assembly

Lay your base rectangle flat. With the right sides of the front panel facing up, pin one of the short ends of the base rectangle to the bottom edge of the front panel. Use your yarn needle and a length of yarn to whipstitch or slip stitch the two pieces together, working through both layers and keeping your stitches even. Repeat with the back panel on the other side of the base rectangle.

Once both panels are attached to the base, fold the bag so the front and back panels are aligned with right sides facing each other. Use stitch markers to pin the side edges together. Beginning at the bottom corner, whipstitch up one side seam, then the other. Turn the bag right side out.

The side seams should sit flat and even. If you notice any puckering, block the seams lightly by misting the bag with water and reshaping it gently. Set it aside to dry.

Attaching the Handles

Thread the top edge of the front panel through one of your bag handles. The handle attachment row you crocheted creates a natural fold-over edge — fold the top of the panel over the lower bar of the handle so the opening you crocheted aligns with the bar, and use a whipstitch or slip stitch to secure the fold in place. Repeat on the back panel with the second handle.

If you are using ring handles, you will thread the crochet top through the ring itself before stitching down the fold. For bamboo D-ring handles, the same approach works well — fold the top edge over the flat bar and stitch it down.

Adding a Lining (Optional but Highly Recommended)

A fabric lining transforms this bag from a crafty project into something that feels polished and professional. It also covers all those ends you wove in and prevents small items from poking through the fabric.

Cut two rectangles of lining fabric, each measuring 12 inches wide by 10 inches tall. Cut one more rectangle measuring 12 by 4 inches for the base.

Sew the base piece to the bottom edges of the two side rectangles, right sides together, using a standard straight stitch and a half-inch seam allowance. Then sew the side seams, again with right sides together. You will have a fabric bag with a flat bottom.

Fold the top edge of the lining down by half an inch, press with an iron, then fold it down again by another half inch so the raw edge is fully enclosed. Press again.

Slide the lining into the crochet bag, wrong sides together, so the folded edge of the lining sits just below the handle attachment area on the inside of the bag. Whipstitch the lining to the crochet bag by hand, working just below the handle fold-over row. Take small, even stitches and try to catch only the back of the crochet stitches so your sewing thread does not show on the outside.

Tips for Keeping Your Scrap Bag Cohesive

One of the most common questions about scrap yarn projects is how to make a finished object that looks intentional rather than chaotic. Here are a few strategies that work well.

Work in a consistent color temperature. If you stick mostly to warm tones — reds, oranges, yellows, warm creams — the bag will feel cohesive even if the individual colors vary widely. The same is true for cool tones. Mixing warm and cool scraps freely tends to feel busier, though it can absolutely be beautiful if that is the aesthetic you are going for.

Vary the stripe widths. If every color change happens after the same number of rows, the bag can look a little mechanical. Let some color sections be wide (four to six rows) and others be narrow (one or two rows) for a more dynamic, organic look.

Include at least one neutral. A few rows of cream, gray, oatmeal, or white throughout the bag act as a visual resting place and help the other colors pop without competing with each other.

Consider texture changes strategically. If you have one yarn that is particularly textured — a boucle, a slub, a plied wool — use it in a single bold stripe rather than mixing it in with everything else. It will read as an intentional design choice rather than an afterthought.

Making This Pattern Your Own

The structure of this pattern is designed to be a jumping-off point, not a fixed prescription. Here are some variations to explore once you have made the basic version.

You can work the panels in the round instead of flat to eliminate the side seams entirely. Begin with a magic ring, work in continuous rounds using whatever stitch sequence you like, and fold the finished tube flat before attaching the base.

For a larger tote bag, increase the starting chain to 51 stitches and work the panels until they measure 14 inches tall. The same handle attachment method works at any size.

For a clutch version, omit the handles entirely and work the panels until they measure 7 inches tall. Add a simple button and loop closure at the center of the top edge.

You can also embellish the finished bag with surface crochet, embroidery, or crochet flowers. This is especially fun if you have small scraps left over after the bag itself is complete — tiny amounts of yarn are all you need for surface work.

Caring for Your Scrap Yarn Bag

Because this bag is made from multiple yarn types and fibers, care instructions will vary. When in doubt, hand wash in cool water with a gentle soap and lay flat to dry. Avoid wringing or twisting the bag, which can distort the shape. If all of your scraps are machine-washable, you can machine wash the finished bag on a gentle cycle in a mesh laundry bag — but check each yarn label before you decide.

If the bag loses its shape over time, a light blocking session will restore it. Wet the bag, reshape it gently, pin it to your blocking mat to your preferred dimensions, and allow it to dry fully before unpinning.

A Note on Zero Waste Crafting

This pattern was built around the idea that the most sustainable yarn is the yarn you already own. Every skein you use from your stash is a skein you do not need to buy — and that matters. It matters for your budget, for the space in your craft room, and for the broader conversation about consumption and creativity.

Zero waste crochet does not mean you never buy new yarn. It means you bring intention to what you already have before reaching for something new. A project like this scrap bag is a beautiful way to practice that intention while making something genuinely useful. It also tends to produce the most personal, story-rich finished objects in your collection — bags made from the remnants of a baby blanket, a sweater for a friend, a holiday stocking, all woven together into something new.

Final Thoughts

This scrap yarn crochet purse is proof that the most interesting projects do not always start with a carefully curated yarn haul. Sometimes they start with a messy basket of leftovers and a willingness to see what happens when you just start crocheting. The alternating single crochet and half double crochet texture, the flat base that gives the bag real structure, the fold-over handle attachment — all of these elements are designed to be forgiving and flexible so that you can focus on the most fun part, which is watching your scraps transform row by row into something you will carry with pride.

Happy crocheting, and happy using every last yard.
