The Ultimate Guide to Knitting a String Market Shopping Bag: Patterns, Tips, and Techniques
There is something deeply satisfying about carrying your groceries home in a bag you made with your own two hands. A knitted string market bag is one of those timeless, practical projects that blends function with craft in the most beautiful way. Whether you are a seasoned knitter looking for your next project or a beginner eager to try something more adventurous, a string market shopping bag is the perfect place to start. These bags are stretchy, durable, eco-friendly, and endlessly customizable. In this guide, we will walk through everything you need to know — from choosing your yarn and needles to following a complete pattern and adding your own personal touches.
Why Knit a String Market Shopping Bag?
Before we dive into the pattern, it is worth taking a moment to appreciate why this project has remained a beloved staple in the knitting community for generations. String market bags, sometimes called net bags or mesh bags, have been used across Europe and beyond for centuries. You have probably seen them piled high with fresh vegetables at a farmers market or slung over someone’s shoulder at a seaside shop. They are lightweight when empty, expand to hold a surprising amount, and they breathe beautifully, which keeps produce fresher than a solid-sided bag.
From a sustainability standpoint, a handknit cotton market bag is one of the most eco-conscious choices you can make. A single reusable bag can replace hundreds of single-use plastic bags over its lifetime, and when you knit your own, you have full control over the materials that go into it. There are no synthetic fibers, no unethical supply chains you cannot trace, and no plastic packaging to throw away.
From a knitting perspective, this project teaches you several valuable skills. You will practice working with simple yarnovers and decreases to create the mesh effect, you will learn to knit in the round, and you will get comfortable with basic shaping. Even if you have only ever knitted scarves and dishcloths, this bag is a very achievable next step.
Choosing Your Yarn
The yarn you choose will make a significant difference in the final look, feel, and function of your bag. For a string market shopping bag, you want something strong, washable, and ideally plant-based.
Cotton yarn is the most popular choice for good reason. It is strong, washable, and gets softer with every use. Look for a 100% cotton yarn in a DK or sport weight for a nice, open mesh. Some knitters prefer a slightly heavier worsted weight cotton if they want a more structured bag with smaller holes.
Hemp yarn is another excellent option. It is extremely strong and durable, even stronger than cotton, and it softens beautifully over time. Hemp has a slightly rougher texture when new but breaks in wonderfully with washing and use. It is also highly sustainable to grow.
Jute twine gives you that classic, rustic string bag look. It is stiffer than cotton or hemp, which means the bag holds its shape well even when empty. Keep in mind that jute is not the most comfortable material to knit with for long sessions, so it works best for shorter projects.
Linen yarn is a luxurious choice with excellent strength and a beautiful drape. It tends to be on the pricier side, but a linen market bag has a refined, polished look that makes it feel like a high-end accessory rather than just a grocery carrier.
For this pattern, we recommend a DK weight 100% cotton yarn in any color you love. You will need approximately 200 to 250 yards for a medium-sized bag that comfortably holds a week’s worth of produce.
Needles and Tools
For DK weight cotton, you will want to use US size 4 (3.5mm) to US size 6 (4mm) circular needles, at least 16 inches long for knitting in the round. If you prefer double-pointed needles, those work perfectly well for the bottom of the bag before you have enough stitches to use a circular needle.
You will also need a yarn needle for weaving in ends, a stitch marker or two to mark the beginning of your rounds, and a pair of scissors. A row counter can be helpful but is entirely optional.
Understanding the Mesh Stitch
The open, net-like texture of a string market bag comes from a simple combination of yarn overs and decreases. A yarn over (YO) creates a new stitch and an eyelet hole, while a knit 2 together (K2tog) or a slip, slip, knit (SSK) removes a stitch to keep your stitch count the same. When these two moves are paired together, they create that beautiful lacy mesh without changing the number of stitches in your round.
The most basic mesh pattern used for market bags looks like this over an even number of stitches:
Round 1: Yarn over, K2tog — repeat to end of round.
Round 2: Knit all stitches.
Alternating these two rounds gives you a diagonal mesh. If you want a more symmetrical mesh, you can alternate the direction of the decrease:
Round 1: YO, K2tog — repeat to end.
Round 3: SSK, YO — repeat to end.
Round 2 and Round 4: Knit all stitches.
Both approaches look wonderful, so choose whichever you prefer. We will use the simpler two-row version for this pattern since it is beginner-friendly and still produces a gorgeous result.
The Complete String Market Shopping Bag Knitting Pattern
Finished Measurements: Approximately 12 inches wide and 14 inches deep when lightly stretched, with a handle length of about 20 inches.
Materials:
- 200–250 yards DK weight 100% cotton yarn
- US size 5 (3.75mm) circular needles, 16 inches
- 2 stitch markers
- Yarn needle
- Scissors
Gauge: Gauge is not critical for this project. A more open mesh will make a larger, stretchier bag. A tighter gauge will make a smaller, sturdier bag.
Abbreviations:
- CO = cast on
- K = knit
- K2tog = knit 2 together
- YO = yarn over
- PM = place marker
- SM = slip marker
- BO = bind off
- St(s) = stitch(es)
- Rnd = round
The Bottom of the Bag
The bag begins with a flat rectangular base knitted back and forth in garter stitch, which gives it structure and stability so your items do not all fall to the bottom center.
CO 10 stitches.
Knit every row (garter stitch) until the piece measures 6 inches from the cast-on edge. This creates a small rectangular panel that forms the base of your bag.
Do not bind off. You will now pick up stitches around all four sides of this rectangle to begin knitting in the round for the body of the bag.
Picking Up Stitches
This is the part that can feel a little daunting if you have not done it before, but it is simpler than it looks. You will pick up stitches along all four edges of your base rectangle to create a continuous loop of stitches.
Along the long side of the rectangle (the row edges), pick up and knit approximately 1 stitch for every 2 rows of garter stitch. Along the short ends (the cast-on and live stitch edge), pick up and knit every stitch.
The exact number is flexible. You want to aim for approximately 60 to 80 stitches total, and crucially, you need an even number so that the YO/K2tog pattern divides evenly.
Place a stitch marker at the beginning of the round.
Knitting the Body
Once you have your stitches picked up and your marker in place, you are ready to start the body of the bag.
Rounds 1–3: Knit all stitches (this creates a small border of stockinette to stabilize the transition from the flat base).
Round 4 onward — Mesh pattern:
- Odd rounds: YO, K2tog repeat to end of round.
- Even rounds: Knit all stitches.
Continue working the mesh pattern until the bag body measures approximately 12 to 14 inches from the base, or until you are happy with the depth of your bag. The mesh is stretchy, so erring on the side of a little longer is always a good idea — you can always fold the top down, but you cannot add length after the fact without ripping back.
The Handles
The handles are where you have the most room for creativity. There are two main approaches: knitted handles and I-cord handles. Knitted handles are made directly as part of the bag body, while I-cord handles are made separately and sewn on. Both are strong and comfortable.
For integrated knitted handles:
After completing the bag body to your desired length, knit one final round of plain knitting. Then, on the next round, divide your stitches roughly in half (half for the front of the bag, half for the back).
On the front half only, bind off the center 20 stitches and knit the remaining stitches on each side back and forth in garter stitch for approximately 8 inches, then join those two side sections together by binding off while knitting them together. This creates a loop that forms the front handle. Repeat on the back half of the bag for the second handle.
For I-cord handles (a cleaner, rounder look):
Using double-pointed needles or a short circular needle, cast on 4 stitches and work I-cord until each handle measures approximately 20 inches. Do not turn your work at the end of each row; instead, slide the stitches back to the right needle tip and pull the working yarn firmly across the back before knitting again. This is what creates the cord effect. Make two handles and sew them firmly to the inside top edge of the bag, approximately 3 inches in from each side edge.
Finishing
Weave in all ends securely with your yarn needle. Cotton yarn has a tendency to slip, so weave the end in one direction, then turn and weave back the other way to lock it in place.
Give the bag a good soak in cool water and gently squeeze out the excess moisture. Lay it flat or drape it over a bowl to block into shape. Cotton will relax and open up beautifully as it dries, and your mesh pattern will become much more visible and uniform.
Pattern Variations and Customization Ideas
One of the joys of knitting your own bag is that no two bags have to look alike. Here are some ways to make this pattern entirely your own.
Stripes: Use two or more colors of cotton yarn and switch at the start of a new mesh round. Because the mesh is worked in a simple two-row repeat, stripes are very easy to incorporate. Even a single contrast-color stripe near the top of the bag looks striking.
Longer or shorter: Adjust the length of the body for a deeper bag that holds more, or a shorter bag for a quick, daily-use tote. You can also make the base rectangle smaller or larger to change the overall proportion.
Smaller mesh holes: If you want a bag with tighter holes (better for carrying smaller items like loose apples or citrus), simply work fewer plain knit rounds between mesh rounds, or switch to a K1, YO, K2tog pattern that spaces out the eyelets differently.
Fringe or tassels: Add fringe to the bottom edge of the bag by cutting lengths of yarn, folding them in half, and pulling them through the cast-on edge with a crochet hook. This adds a bohemian, artisan look that suits natural-colored cotton or hemp beautifully.
Embroidery accents: Once your bag is finished and blocked, you can add simple embroidered motifs — small flowers, geometric shapes, or initials — using a contrasting cotton yarn and a yarn needle.
Caring for Your Knitted Market Bag
A well-knitted cotton market bag can last for years with proper care. Most cotton yarns are machine washable on a gentle or delicate cycle, but hand washing will help preserve the elasticity of the knitting and keep the fibers in the best condition for longer. Use a mild detergent and cool water, never hot water, which can cause cotton to shrink.
After washing, reshape the bag while it is still damp and allow it to air dry. Avoid wringing it out, which can distort the stitches. Once dry, store the bag folded or rolled, and it will be ready to sling over your arm the next time you head to the market.
A Note on Gifting Knitted Market Bags
Handknitted string market bags make some of the most thoughtful, practical gifts you can give. They are suitable for almost anyone — a new homeowner, a friend who is trying to reduce plastic use, a grandmother who loves farmers markets, or a colleague with a kitchen garden. Pair the finished bag with a bunch of fresh flowers, a selection of local produce, or a beautiful bar of artisan soap tucked inside, and you have a truly personal, eco-conscious gift that took skill and time to make.
If you plan to sell your knitted bags, keep in mind the time involved and price your work accordingly. A hand-knitted cotton market bag represents several hours of work and the cost of quality materials. Do not undervalue your craft.
Final Thoughts
Knitting a string market shopping bag is one of those projects that rewards you long after the final stitch is cast off. Every time you take it to the market, you carry with you something you made — something useful, sustainable, and beautiful. The pattern is simple enough to become meditative once you find your rhythm with the mesh rows, and it is satisfying in a way that only genuinely functional handmade objects can be.
Whether you follow this pattern exactly or use it as a jumping-off point for your own creativity, the most important thing is to enjoy the process. Cast on, knit a few rounds, feel the cotton moving through your fingers, and let yourself settle into the rhythm of it. Your market bag will be finished before you know it, and you will almost certainly want to start a second one.
Happy knitting.
