Why You’ll Love This Square Crochet Basket Pattern

Before we dive into the actual pattern, let’s talk about why a square basket might be exactly what your home needs right now.

Round baskets are charming, but square baskets are genuinely more practical for most storage situations. They fit neatly into corners, line up side by side on shelves without wasted space, and hold rectangular items like books, folded cloth diapers, or stacks of yarn far more efficiently. When you crochet your own, you also get to choose the exact size, color, and texture — which means no more hunting through home goods stores hoping something close enough turns up.

This pattern uses a simple stitch structure that even confident beginners can handle. If you’ve completed a few basic projects and you’re comfortable with single crochets and working in continuous rounds, you’re ready for this. The stitch that makes this basket its wonderfully textured exterior is straightforward to learn, and once you get into a rhythm, your hands will practically move on their own.

The construction method is also designed to give the basket natural structure without needing any internal support like a wire frame or cardboard insert. The right yarn choice and tension do all the heavy lifting, giving you walls that stand upright on their own and a flat base that won’t curl or bunch.

Materials You’ll Need

Getting your materials together before you start is always a good idea with any project, but especially with a structured piece like this basket. Here’s what you’ll want to have on hand.

Yarn: You’ll want a bulky or super bulky weight yarn for this pattern. Anything in the weight 5 or 6 range works wonderfully. Cotton rope yarn, thick cotton yarn, and even recycled t-shirt yarn give you that firm, structured result that makes a storage basket actually functional. Look for something with a bit of stiffness to it rather than a soft, drapey yarn — the basket needs to hold its shape when it’s full. A single skein of 200 to 250 yards will typically be enough for a small to medium basket, but having an extra skein on hand is never a bad idea.

Hook: A 6mm, 7mm, or 8mm crochet hook depending on your yarn weight and tension. Check your yarn label for guidance, but for most bulky basket yarns, a 7mm or 8mm hook tends to produce the firmest fabric with the best structure. If your basket walls feel floppy or loose, go down a hook size. If your stitches are so tight it’s hard to insert the hook, go up a size.

Scissors: A sharp pair for clean cuts.

Yarn needle: For weaving in your ends cleanly at the finish.

Stitch markers: Optional but helpful for marking the corners of your square base as you build it out.

Gauge and Sizing

Gauge matters more for wearables than for home goods, but since you’re making a basket with a specific size in mind, it’s worth doing a quick check.

For this pattern, aim for approximately 10 single crochets and 11 rows to equal about 4 inches with your chosen yarn and hook. If your gauge is slightly off, the basket will simply be a little bigger or smaller, which is usually fine for a storage piece. If it’s significantly different, adjust your hook size.

The finished basket from this pattern measures approximately 8 inches square at the base and stands about 6 inches tall. If you want a smaller basket — perfect for holding a remote control, small toys, or a collection of chapsticks — you can work fewer stitches for the base. For a larger laundry-style basket, increase your starting chain and add more rounds to the walls.

Stitch Abbreviations

Throughout this pattern, the following abbreviations are used:

CH = chain
SL ST = slip stitch
SC = single crochet
HDC = half double crochet
ST = stitch
BLO = back loop only
SP = space
RND = round
SK = skip

The Pattern: Square Crochet Storage Basket

Part One: The Base

The base of this basket is worked flat in rows, which is what gives it that clean, square shape from the start. Unlike a round basket that begins in a magic ring and spirals outward, the square base starts with a foundation chain and grows in even rows until you have a neat square.

Foundation Chain: Chain 21. (This gives you a working chain that produces a base of about 8 inches. Adjust up or down in increments of 2 chains to resize.)

Row 1: Starting in the second chain from the hook, SC in each chain across. Turn. (20 SC)

Row 2: CH 1, SC in each stitch across. Turn. (20 SC)

Rows 3 through 20: Repeat Row 2. You’ll continue working back and forth in single crochet until your piece measures approximately as wide as it is long — in other words, until it forms a square. This should be around 20 rows total, but count your stitches as you go and use a measuring tape to check the shape. A true square base makes the rest of the construction much easier.

When your base is square, do not fasten off.

Part Two: The Sides

Now comes the satisfying part — turning your flat square into a 3D basket. You’ll do this by working around the perimeter of your base and then building upward in continuous rounds.

Set Up Round: CH 1. You’re going to work SC evenly around all four sides of your base. Down the first long edge, work 1 SC per row end (approximately 20 SC). At the corner, work 3 SC in the corner stitch to turn. Along the foundation chain edge, work 1 SC per chain stitch across (20 SC). Work 3 SC in that corner. Back up the other long edge, work 1 SC per row end (20 SC). Work 3 SC in the corner. Across the last edge (the top of your last row), work 1 SC per stitch (20 SC). Work 3 SC in the final corner. Join with a SL ST to the first SC of the round, or place a stitch marker to work in continuous rounds — either method works.

If you’re working in continuous rounds (recommended for a neater result), do not join or chain at the end of each round. Simply keep going and move your stitch marker up each round.

Rounds 1 through 12 (Sides): SC in BLO in each stitch around.

Working through the back loop only is what creates that beautiful ridged texture you often see on high-end crochet baskets. It also adds structure to the walls. At each corner, you’ll continue to work 3 SC in the center stitch of the 3-SC corner group from the set-up round — this is what keeps the basket expanding at the corners and maintains the square shape as the walls rise.

As you work, check periodically that your corners are sitting at clean 90-degree angles. If they start to round out, your corner increases may need adjustment.

After 12 rounds of the BLO single crochet, your basket walls will be approximately 5 to 6 inches tall. If you’d like a taller basket, simply continue working in this pattern until you reach your desired height.

Part Three: The Rim

The rim finishes the top of the basket with a tidy, slightly firmer edge that helps the walls stay upright and gives the finished piece a polished look.

Rim Round 1: CH 1, work 1 HDC in each stitch around, working through both loops this time (not BLO). At each corner, work 2 HDC in the center corner stitch. Join with SL ST to the first HDC.

Rim Round 2: CH 1, work 1 SC in each stitch around, working through both loops. Do not increase at corners in this round. Join with SL ST to the first SC.

Fasten off and leave a tail of about 6 inches for weaving in.

Finishing

Weave in all your ends thoroughly using your yarn needle. For a basket that will get regular use, it’s worth weaving each end in two different directions to make sure it won’t work loose over time.

If your basket needs a little help holding its shape, you can block it by dampening it with cool water, gently shaping it by hand into a perfect square with upright sides, and allowing it to air dry completely. Cotton yarns respond particularly well to wet blocking and will firm up nicely as they dry.

Tips for Making This Basket Even Better

Over the years of making and testing this pattern, a few tips have come up again and again that make a real difference in the finished result.

Tension consistency is everything with a structured piece like this. If you notice your tension changing — looser when you’re tired, tighter when you’re watching something intense on TV — take a break and come back fresh. Inconsistent tension shows up more obviously in a basket than in a scarf.

Yarn choice truly matters for this project more than most. A yarn that has some natural stiffness, like cotton or a cotton-blend, will give you a basket that stands up on its own. A yarn that’s soft and stretchy, like acrylic with a lot of give, will produce a basket that flops to the side when it’s empty. That’s not necessarily a dealbreaker — a slightly soft basket can still be beautiful and functional — but if you want true structure, choose accordingly.

Color changes can add a lot of personality to this basket without adding much complexity. Try switching colors at the start of a new round to create simple stripes on the walls, or use one color for the base and another for the sides. Joining a new color is as simple as making your final pull-through of one color with the new color’s yarn.

Sizing up is very straightforward with this pattern. To make a laundry basket or a toy chest, start with a longer foundation chain (try 41 or 51 chains) and work more rows for the base to match. Then simply add more rounds to the walls. The construction method scales beautifully.

Creative Ways to Use Your Square Crochet Storage Basket

One of the best things about making your own storage baskets is that you can tailor them exactly to what you need. Here are some ideas that have been popular with the Krissy’s Over The Mountain Crochet community.

Nursery organization is one of the most common uses for these baskets. A set of three in coordinating colors — one for small toys, one for burp cloths, one for board books — looks absolutely beautiful on a nursery shelf and is endlessly practical. Parents love that a handmade basket can be washed if needed and doesn’t contain any synthetic materials that might bother a sensitive baby.

Craft room storage is another winner. Use a medium-sized basket for holding balls of yarn, a smaller one for keeping scissors, stitch markers, and hooks all in one spot, and a larger version for storing works in progress.

Entryway organization benefits from a sturdy square basket for holding things like mail, keys, sunglasses, and small items that tend to collect near the front door. A larger version is perfect for a catch-all for scarves, gloves, and hats during winter months.

Kitchen use might not be the first thing you think of, but these baskets are wonderful for holding cloth napkins, small packets of tea, or fruit on the counter. A lined version (simply sew a simple fabric liner and drop it in) is practical for holding bread or rolls.

Gift giving is where these baskets really shine. Fill a finished basket with thoughtful items — bath products, snacks, craft supplies — and you have a gift that keeps on giving long after the contents are used up. The basket itself becomes part of the present.

Frequently Asked Questions

Can a beginner make this basket? If you’re comfortable with single crochet and have completed at least a few projects, this is absolutely within reach. The skills required are basic, and the pattern is written to be easy to follow step by step.

What if my basket won’t stand up on its own? This usually comes down to yarn choice or tension. Try a stiffer yarn or tighten your tension slightly by going down a hook size.

Can I use two strands of worsted weight yarn held together? Yes, this works beautifully and is a great way to use up stash yarn. Two strands of standard worsted weight held together behave similarly to a single strand of bulky yarn and will give you a firm, structured fabric.

How do I wash a finished basket? For cotton yarn, a gentle machine wash on cold and air dry usually works well. Always check your specific yarn’s care label before washing.

Can I add handles? Absolutely. A simple way to add handles is to chain a length of approximately 20 to 25 chains, skip an equal number of stitches along the rim, and join back to the rim with a slip stitch. Work SC along the chain on the return to reinforce it. Repeat on the opposite side for a matching pair of handles.

Final Thoughts

This square crochet storage basket pattern is one of those reliable, revisit-it-often patterns that earns a permanent spot in your project folder. It’s fast enough to make in an evening or a weekend, satisfying enough to keep you engaged from start to finish, and useful enough that you’ll find reasons to make it again and again.

Whether you’re making one for yourself, a set for a gift, or a whole collection for a nursery, every single basket you finish will feel like a small victory — something handmade, useful, and entirely your own.
