The Complete Guide to Crocheting an Onion Storage Bag: Keep Your Kitchen Organized and Your Onions Fresh

If you’ve been looking for a practical, beautiful, and eco-friendly way to store your onions, garlic, and other root vegetables, a crocheted onion storage bag might be exactly what you need. These open-weave bags have been a kitchen staple for generations, and with good reason — they allow air to circulate around your vegetables, preventing moisture buildup and extending shelf life significantly. Best of all, you can make one yourself in just a few hours, even if you’re a beginner crocheter.

In this complete guide, we’ll walk you through everything you need to know about crocheted onion storage: why it works, what materials to choose, step-by-step instructions for making your own bag, tips for customizing your design, and how to care for it over time. Whether you’re new to crochet or an experienced maker looking for a satisfying practical project, this guide has everything you need.

Why Crochet an Onion Storage Bag?

Before we dive into the pattern, let’s talk about why a crocheted bag is one of the best ways to store onions and other alliums like shallots, garlic, and leeks.

Onions need airflow. Unlike many vegetables that do well in sealed containers or the refrigerator, whole onions prefer cool, dry, well-ventilated conditions. When onions are stored in plastic bags or closed containers, moisture accumulates and causes them to soften, mold, and sprout much faster than they should. A mesh or open-weave bag solves this problem naturally by allowing constant air circulation on all sides.

Beyond the practical benefits, a handmade crochet bag adds a touch of warmth and craftsmanship to your kitchen. Hung from a hook or draped in a basket, these bags look charming displayed openly — a far cry from stuffing vegetables into a drawer or a plastic produce bag from the grocery store. They’re also a wonderful zero-waste alternative to single-use plastic. Once you make a few, you may never reach for a plastic produce bag again.

Crocheted vegetable bags also make thoughtful, practical gifts. A set of two or three bags in natural cotton, tied together with a ribbon, makes a lovely housewarming or hostess gift that any home cook will appreciate and actually use.

Choosing the Right Yarn and Hook

The yarn you choose will make a significant difference in how your bag performs. For anything that will come into contact with food or hang in your kitchen, natural fibers are always the best choice.

Cotton yarn is the gold standard for kitchen storage bags. It’s breathable, washable, sturdy, and gets softer with each wash. Look for 100% cotton yarn in a worsted or bulky weight for bags you’ll use for heavy vegetables like onions. A thicker cotton twine or kitchen cotton will hold up especially well over time. Popular choices include Sugar ‘n Cream, Lion Brand 24/7 Cotton, and Paintbox Simply DK Cotton.

Jute and hemp yarn are also excellent options. They’re naturally rough-textured and extremely durable, giving your finished bag a rustic, earthy look that suits a farmhouse-style kitchen beautifully. Keep in mind that jute can be a bit scratchy to work with, so you may want to wear a thimble or take breaks if your hands are sensitive. Hemp softens considerably after washing.

Linen yarn falls somewhere in between cotton and jute — it has a lovely natural drape, wears incredibly well, and produces a slightly more polished-looking finished bag.

Avoid acrylic or synthetic yarns for this project. While they’re perfectly suitable for many crochet projects, they don’t breathe well and aren’t ideal for food storage applications. They also tend to stretch and lose their shape more quickly under the weight of vegetables.

For a standard onion bag that holds about 3 to 5 onions comfortably, you’ll need roughly 100 to 150 yards of worsted-weight cotton yarn or twine. For a larger market-style bag, plan for 200 to 250 yards.

As for hooks, choose a size that creates an open but sturdy mesh. For worsted-weight cotton, a 5mm (H/8) or 5.5mm (I/9) hook works well. If you’re using a chunkier twine or jute, step up to a 6mm (J/10). The goal is a mesh that’s open enough to allow airflow and let you see what’s inside, but tight enough that onions won’t slip through the gaps.

What You’ll Need

Here’s a simple supply list before you get started:

You’ll need about 100 to 150 yards of 100% cotton worsted-weight yarn or cotton kitchen twine in your chosen color, a crochet hook sized 5mm to 6mm depending on your yarn, a yarn needle for weaving in ends, a pair of scissors, and an optional stitch marker to keep track of your rounds. You may also want a length of coordinating ribbon or cord for the drawstring closure, though a crocheted drawstring works just as well.

Understanding the Basic Mesh Stitch

The most common stitch used for vegetable storage bags is a simple chain-space mesh. If you’ve ever made a granny square or worked with chain loops, this will feel very familiar. The basic structure repeats across every row or round: you make a stitch, skip a stitch or two, chain a few, and repeat. This creates the open, lacy grid that lets air flow through while still holding your vegetables securely.

The mesh can be worked flat (in rows) and then seamed together, or it can be worked in the round from the bottom up. Working in the round produces a seamless bag with no seam to sew, which many crocheters prefer. We’ll use the in-the-round method here.

If you’re a beginner, take a few minutes to practice the chain-space mesh on a swatch before starting the bag. Work about 20 chains, then try a row of “sc, ch 2, skip 2, repeat across.” Once you’re comfortable with the rhythm, the bag itself will work up quickly.

Step-by-Step Crochet Onion Bag Pattern

This pattern creates a bag approximately 10 inches tall and 8 inches wide when laid flat, which is a good size for storing 4 to 6 medium onions or a full head of garlic plus a few shallots. The finished bag has an open mesh body and a simple drawstring closure at the top.

Gauge: 14 stitches and 16 rows = 4 inches in single crochet with worsted-weight cotton and a 5mm hook. Gauge is not critical for this project, but it will affect your finished size.

Abbreviations: ch = chain, sl st = slip stitch, sc = single crochet, dc = double crochet, sp = space, st = stitch, rep = repeat.

Start with the base. Make a magic ring, or chain 4 and join with a slip stitch to form a small ring. Round 1: chain 3 (counts as first dc), work 11 more double crochets into the ring — 12 dc total. Join with a slip stitch to the top of the starting chain-3.

Round 2: Chain 3, dc in the same stitch. Work 2 dc in each stitch around — 24 dc total. Join with slip stitch.

Round 3: Chain 3, dc in the same stitch. Dc in next stitch, 2 dc in next stitch. Repeat from around — 36 dc total. Join.

Round 4: Chain 3, dc in next 2 stitches. 2 dc in next, dc in next 2. Repeat from around — 48 dc total. Join with slip stitch. This completes your circular base.

Build the mesh body. Now you’ll transition into the open mesh pattern that forms the main body of the bag.

Round 5 (transition round): Chain 1, sc in the same stitch. Chain 3, skip 2 stitches, sc in next stitch. Repeat from around. End with chain 3, skip 2, join with slip stitch to first sc.

Round 6 and all subsequent rounds: Slip stitch into the center of the first chain-3 space. Chain 1, sc in the same space. Chain 3, sc in next chain-3 space. Repeat from around. Join with slip stitch to first sc.

Repeat Round 6 until your bag measures approximately 9 inches from the base. This will take roughly 18 to 22 rounds depending on your tension and yarn weight. The beauty of this pattern is that you can make your bag as tall or as short as you like — just keep going until you’re happy with the length.

Create the drawstring channel. When your bag reaches the desired height, you’ll add a drawstring channel at the top.

Next round: Chain 1, sc in each stitch and chain space around, working 1 sc into each chain-3 space and 1 sc into each sc. Join. You should have roughly 48 sc around.

Drawstring round: Chain 5, skip 4 stitches, dc in next stitch. Chain 2, skip 2 stitches, dc in next stitch. Repeat from around. Join with slip stitch to the 3rd chain of starting chain-5.

Next round: Chain 1, sc evenly around, working into the chain-2 spaces and the dc stitches. Join and fasten off.

Make the drawstring. You have a few options here. The simplest is to cut a length of yarn about 36 inches long, fold it in half, and use a crochet hook to twist it into a simple cord. Alternatively, chain 100 and fasten off for a soft crocheted drawstring. You can also use a length of ribbon, twine, or leather cord. Weave the drawstring through the chain-2 spaces in the drawstring round, going in and out around the full circumference of the bag. Tie the ends together or attach a small button or bead as a stopper.

Weave in all your ends securely with a yarn needle, give your bag a gentle blocking if needed, and it’s ready to use.

Tips for Customizing Your Onion Storage Bag

One of the great joys of making your own storage bags is that you can customize them completely to suit your kitchen and your needs.

For a larger bag capable of holding a full 3-pound bag of onions, simply work more increase rounds at the base to widen it, and add more rounds in the body section. A base with 60 to 72 stitches gives you a roomier bag that works beautifully for larger vegetables like butternut squash or sweet potatoes as well.

For a smaller garlic bag, stop the increases after Round 2 (24 dc) and keep the body section to about 5 inches tall. A small bag like this is perfect for hanging a few heads of garlic near the stove where you can grab one easily while cooking.

Color is another fun variable. Natural undyed cotton or jute gives you the most rustic, organic look, but there’s no reason you can’t use a soft sage green, warm terracotta, or even a classic navy if it suits your kitchen aesthetic better. If you’re making a set of bags for different vegetables, consider using a different color for each so you can identify them at a glance.

You can also add embellishments like a small crocheted flower or leaf on the side of the bag, a wooden ring for hanging, or a woven leather handle. Some crocheters like to add a small fabric label stitched to the side that says “Onions,” “Garlic,” or “Shallots” — a nice touch if you’re making bags as gifts.

How to Store Onions Properly in Your Crocheted Bag

Making a beautiful bag is only half the equation — knowing how to use it correctly will ensure your onions stay fresh for as long as possible.

Hang your bag or set it in a cool, dry, dark spot. A pantry shelf, a hook inside a cabinet door, or a spot on your kitchen wall away from direct sunlight all work well. The ideal storage temperature for onions is between 45°F and 55°F (7°C to 13°C), though room temperature is perfectly fine for short-term storage of a week or two.

Never store onions in the refrigerator (unless they’ve already been cut), and never store them next to potatoes. Onions release ethylene gas and moisture that cause potatoes to sprout faster, and potatoes release moisture that causes onions to rot. Keep them separated.

Check your bag every few days and remove any onions that are starting to soften or sprout before they affect the rest. One bad onion really can spoil the bunch when they’re in close contact.

Caring for Your Crochet Onion Bag

One of the great advantages of cotton yarn is that it’s fully machine washable. When your bag needs cleaning — which happens inevitably with kitchen items — toss it in the washing machine on a gentle cycle with cold water. Lay it flat to dry or hang it up, and it will be ready to use again in no time.

If you’ve used jute or hemp, hand wash your bag instead, as these fibers can become brittle if machine washed repeatedly. A gentle squeeze in cool soapy water followed by air drying is all they need.

Over time, cotton bags may develop a slight yellow tint from contact with onion skins. This is completely harmless and actually gives the bag a lovely, well-loved patina. If you prefer to keep it looking crisp, soak it in a mixture of warm water and white vinegar for 30 minutes before washing.

Making a Set: A Whole Kitchen Collection

Once you’ve made your first onion bag, chances are you’ll want to keep going. The same basic pattern works beautifully for garlic, shallots, potatoes, citrus fruit, winter squash, and even bread rolls. A matching set of storage bags in the same yarn but varying sizes looks stunning hung together in a cluster on a kitchen wall or displayed in a large wooden bowl on the counter.

Consider making a dedicated bag for garlic in a small size, a medium bag for shallots or a few onions, and a large bag for a full onion harvest or a big batch of potatoes. If you grow your own vegetables or shop at a farmers market, having a collection of handmade bags ready to go transforms the whole experience of bringing produce home.

These bags also make wonderful items to sell at craft fairs, farmers markets, or on platforms like Etsy. They’re quick to make, cost relatively little in materials, and appeal strongly to buyers who are interested in sustainable, plastic-free living. A set of three in natural cotton can easily sell for $20 to $30, making them a satisfying small business product for a maker looking to earn a little extra from their craft.

Final Thoughts

A crocheted onion storage bag is one of those projects that sits at the perfect intersection of beautiful and useful. It takes only a few hours to complete, costs very little in materials, and produces something you’ll reach for every single week in your kitchen. It’s the kind of handmade item that earns its place in your home not because it’s decorative but because it genuinely works better than the alternatives.

Whether you’re making one for yourself, gifting a set to a friend who loves to cook, or adding them to your craft fair lineup, these bags represent crochet at its most practical and satisfying. Pick up some cotton yarn, find a comfortable hook, and give it a try. Once you’ve crocheted your first onion bag, you’ll wonder how your kitchen ever functioned without one.
