How To Knit A Market String Bag

There is something deeply satisfying about walking into a farmers market or grocery store with a bag you made yourself. It stretches to hold more than you expect, it washes beautifully, it lasts for years, and every time someone asks where you got it, you get to say you made it. A market string bag is one of those projects that looks impressive but is actually very beginner-friendly once you understand the structure. If you have ever wanted to try knitting something practical and beautiful at the same time, this is the project for you.

In this tutorial, I am going to walk you through everything you need to know to knit your own market string bag from start to finish. We will cover the materials, the techniques, the pattern, and plenty of tips along the way so that even if you are fairly new to knitting, you can tackle this project with confidence.

Why Knit A Market String Bag?

Before we get into the how, let me take a moment to talk about the why. We are all trying to use fewer single-use plastic bags, and reusable bags are a wonderful solution. But the ones you buy at the grocery store checkout are often made from synthetic materials, they pill, they lose their shape, and honestly, they are not very exciting.

A hand-knit market bag made from cotton or linen yarn is different. Natural fiber string bags are strong, washable, breathable, and genuinely beautiful. They fold up small enough to fit in your purse or pocket, so you always have one on hand. They expand to hold a surprising amount of groceries, produce, or anything else you want to carry. And because you made them yourself, they have a warmth and meaning that no store-bought bag ever will.

This pattern also makes a wonderful gift. New parents, teachers, farmers market enthusiasts, eco-conscious friends — just about everyone will appreciate a hand-knit bag. Once you learn the pattern, you can knock one out in a weekend and have a go-to gift ready whenever you need it.

Materials You Will Need

Getting your materials right makes a big difference with this kind of project. Here is what I recommend.

Yarn: Choose a smooth, sturdy cotton or linen yarn in a fingering or DK weight. Cotton is the most popular choice for market bags because it is affordable, widely available, easy to wash, and comes in beautiful colors. Linen is a bit stiffer when you first start working with it but softens with washing and is incredibly strong. Avoid anything too fluffy or fuzzy — you want a yarn with good stitch definition so the open mesh pattern shows clearly. A single skein of around 200 to 300 yards is usually plenty for a standard market bag.

Some yarn brands I love for this type of project include Lion Brand 24/7 Cotton, Paintbox Simply DK Cotton, and We Are Knitters The Cotton. All of these are smooth, affordable, and wash beautifully.

Needles: You will want circular needles in a size that gives you a relaxed, open fabric — typically one or two sizes larger than what the yarn label recommends. If your yarn suggests a US size 4 (3.5mm), try a US size 6 (4mm) or even a US size 7 (4.5mm). The slight looseness in the fabric is what gives the bag its stretch and mesh-like quality. For a standard market bag, 16-inch circular needles work well for the body, and you will need double-pointed needles or a longer circular for magic loop for the base.

Other supplies: You will also need a tapestry needle for weaving in ends, scissors, stitch markers (at least four), and a measuring tape.

Understanding The Structure Of A Market Bag

Most knitted market bags are worked in the round from the bottom up, meaning you start with the base, build up the sides using a mesh or eyelet pattern, and finish with handles at the top. Some patterns are worked from the top down, but bottom-up construction tends to give a more structured base and is easier to adjust for size as you go.

The mesh body of the bag is created using simple yarn overs and decreases. A yarn over adds a stitch (and creates a hole), and a decrease removes a stitch, keeping your total stitch count the same. Alternating these two movements creates that classic open lacework that is both stretchy and beautiful. You do not need to know how to knit lace to do this — the mesh used in most market bag patterns is much simpler than traditional lace and uses just a couple of basic stitches.

The handles are typically created by casting off stitches and then casting them back on in the next row to form loops, or by working an i-cord bind off. Some patterns knit the handles as separate pieces and seam them on. The method used in this tutorial creates a simple, sturdy looped handle that requires no seaming.

The Pattern

This pattern creates a market bag that is approximately 10 inches wide and 12 inches deep when relaxed, and it will stretch to hold significantly more when loaded up. It is worked in the round on circular needles.

Abbreviations

CO — cast on
K — knit
P — purl
YO — yarn over
K2tog — knit two stitches together
PM — place marker
SM — slip marker
BO — bind off
RS — right side
WS — wrong side

Gauge

Gauge is not critical for this project, but you are aiming for a relaxed, open fabric with about 18 stitches and 24 rows to 4 inches in stockinette on your chosen needle size. Swatch if you want to adjust the finished size.

Step One: Cast On And Work The Base

Using double-pointed needles or the magic loop method with a long circular needle, cast on 8 stitches. Divide them evenly across your needles — 2 stitches per needle if using DPNs, or 4 stitches on each side if using magic loop. Place a marker and join to work in the round, being careful not to twist.

Round 1: Knit all stitches.

Round 2 (increase round): (K1, YO) repeat to end of round. You now have 16 stitches.

Round 3: Knit all stitches.

Round 4 (increase round): (K1, YO) repeat to end of round. You now have 32 stitches.

Round 5: Knit all stitches.

Round 6 (increase round): (K2, YO) repeat to end of round. You now have 48 stitches.

Rounds 7–8: Knit all stitches.

Round 9 (increase round): (K3, YO) repeat to end of round. You now have 64 stitches.

Rounds 10–12: Knit all stitches.

At this point your base should measure roughly 3 to 4 inches in diameter. If you want a larger, more structured base, continue working increase rounds, spacing the increases further apart each time, until you reach your desired diameter.

Step Two: Transition To The Sides

Now that your base is complete, you will transition to working the sides of the bag straight upward without further shaping.

Switch to your 16-inch circular needles if you have been using DPNs.

Setup round: Divide your 64 stitches into four equal sections of 16 stitches each and place a stitch marker at each division. This will help you keep track of your mesh pattern.

Step Three: Work The Mesh Body

The mesh pattern is worked over a multiple of 2 stitches and is very simple.

Mesh Round 1: (YO, K2tog) repeat to end of round.

Mesh Round 2: Knit all stitches.

Repeat these two rounds until the bag measures approximately 10 to 11 inches from where you started the sides. This is the main body of the bag, and it goes quickly once you get into the rhythm. The alternating mesh and plain knit rounds create a beautiful, stretchy fabric that is strong enough to carry heavy produce but open enough to show off what is inside.

As you work, you will notice the fabric curling slightly inward at the top. This is normal — it will be corrected when you work the top border.

Step Four: Work The Top Border

Once your bag body has reached the desired length, work a plain knit border of about 6 to 8 rounds. This stabilizes the top edge of the bag and gives the handles something solid to attach to.

Rounds 1–6: Knit all stitches.

You can also work a couple of purl rounds here if you want a decorative rolled edge. Simply purl 2 rounds, then knit 2 rounds, then purl 2 rounds for a pretty, subtle detail.

Step Five: Create The Handles

This is the moment that transforms your knitted tube into a market bag. The handles are created by binding off a section of stitches on each side and then casting them back on.

Handle Round:

Knit to the first marker. Bind off 10 stitches. Knit until you are 5 stitches past the second marker. Bind off 10 stitches. Knit to end of round.

On the next round, when you reach a gap where you bound off, cast on 10 stitches using the backward loop (or thumb) cast on method. This creates your handle loop on each side.

Knit 4 more rounds over the cast-on stitches to reinforce the handles.

Bind off all stitches loosely.

Step Six: Finishing

Cut your yarn leaving a 6-inch tail. Thread the tail onto your tapestry needle and weave it in securely. Weave in any other ends from your cast-on and any yarn joins.

Block your bag if you like by soaking it in cool water, gently squeezing out the excess moisture, and laying it flat to dry. Blocking opens up the mesh pattern beautifully and makes the finished bag look polished and intentional.

Tips For Success

Tension matters more than you think. A common mistake beginners make with mesh patterns is knitting too tightly. If your yarn overs feel difficult to work into on the following round, loosen up. The whole beauty of a string bag lies in its openness and stretch, and that only happens if your tension is relaxed.

Count your stitches regularly. Yarn overs and decreases can slip away from you if you are not paying attention, and even one missed yarn over or decrease will start to shift your stitch count and throw off the mesh alignment. Take a moment every few inches to count your stitches and make sure you still have 64.

Use stitch markers generously. Even experienced knitters find it helpful to have a marker every 16 stitches when working mesh. It breaks the pattern into manageable chunks and makes it easy to spot if something has gone wrong.

Swatch for size. If you want a larger bag for carrying bigger hauls, simply cast on more stitches for the base and work additional increase rounds. The mesh pattern works over any multiple of 2 stitches, so it is very easy to scale up or down.

Try different colors. One of the nicest things about this project is that even a subtle color change makes it feel completely different. Try a neutral cream or tan for a farmers market aesthetic, a bright citrus color for something cheerful, or a deep jewel tone for a more sophisticated look.

Caring For Your Knit Market Bag

Cotton and linen bags are wonderfully easy to care for. Toss them in the washing machine on a gentle or delicate cycle in cool water, and either lay flat to dry or hang them up. Avoid the dryer if possible — while cotton can handle some heat, air drying is better for the longevity of your bag and helps preserve the open mesh structure.

If you notice any loose loops or small holes forming over time, that is usually just a result of heavy use and is easy to fix by threading a tapestry needle with a matching yarn and working a few small stitches to stabilize the area.

Variations To Try Once You Have Mastered The Basic Bag

Once you have made one market bag and feel comfortable with the construction, there is a whole world of variations to explore.

You can experiment with different mesh patterns. A simple (K1, YO, K2tog) repeat gives a slightly different look than the basic (YO, K2tog). A larger mesh with (YO, K3tog) creates bigger holes and a lacier feel. Search for simple lace stitch patterns and try substituting them into the body of the bag to create something uniquely your own.

You can add a drawstring at the top instead of looped handles. Work a row of evenly spaced eyelets along the top border by replacing a plain knit round with a (K2, YO, K2tog) repeat, then thread a length of i-cord or ribbon through the holes.

You can also work a striped bag by alternating two colors every few rounds. Because you are working in the round, the color changes are seamless and beautiful. A two-tone bag with a natural cotton base color and a bright accent is a classic combination that never looks dated.

Final Thoughts

Knitting a market string bag is one of those projects that gives back far more than it asks of you. The pattern is simple enough to be meditative and satisfying, the finished object is genuinely useful, and the whole project can be completed in just a few evenings of comfortable knitting. Once you make one for yourself, you will very likely find yourself making several more as gifts.

The most important thing is to cast on and get started. Do not worry about perfection on your first bag — the mesh pattern is very forgiving, and even an imperfect bag will be beautiful and functional. Knitting is one of those crafts where experience builds quickly, and by the time you bind off your first bag, you will already have ideas for how you want to approach the next one.

Happy knitting, and enjoy every trip to the market with your beautiful, hand-made bag in hand.
