This crocheted cover will really come in handy when you’d like to disguise a block of craft foam in a soft, unbreakable box-like container. You can also use it for covering assorted other boxes or square objects.

Crochet-covered craft foam has a wide variety of potential uses. I’ve used mine to create several fun candy dispensers. (See photos.) You could use it for silk or dried flower arrangements and many other crafts. I am sure you can think of some amazing ways to put this pattern to good use!

Design in a Nutshell:

Basically, the idea here is to crochet a flat piece shaped like a wide plus-sign. ( + ) The center will be a square, and the square will have extensions emanating out from each side. The extensions will then be folded up and stitched together to form the box.

I’m going to show you a very simple way of making this type of design. It’s rather plain, and could easily be improved on. Once you get the basic idea, feel free to dress it up with beads, fancier stitches, different color patterns, embroidery, appliques, or 3-dimensional embellishments.

Pattern Update: This pattern was updated Dec 1, 2011. If you have a copy of the pattern that was printed prior to that, please either print out a new copy or update your old copy with the fix. The update was made to fix a problem with round 1; 2 dc stitches were accidentally omitted from the pattern. I also added several clarifications throughout. I am terribly sorry for any inconvenience these omissions may have caused.


  • Yarn, thread or fiber in two colors. The second color can be scrap yarn, because you only need a small amount of it.
  • A crochet hook of appropriate size to use with your chosen fiber.
  • A tapestry needle for weaving in ends and stitching the sides of the box together.

My sample was worked in worsted weight cotton yarn, with a size H / 8 – 5.0 mm crochet hook. Feel free to experiment with other fibers and yarn / thread sizes.


This project can be worked at any gauge.

Finished Size:

Finished size will vary, depending on materials used and other factors.

My sample box measures approximately 4 inches high and 4 inches in diameter when it is stretched to its max with the foam block inside it. When laid flat, it is slightly smaller.

Abbreviations Used in This Pattern:

Project Instructions:

Start by making a square. Pretty much any square will do. I’ll share instructions for the one I used, but there’s nothing magical about this square. You can use any square you like.

With main color, ch 5. Join with a sl st to form a ring.

Round 1: Ch 3 – this counts as the first dc. Work 2 more dc in ring, (ch 2, 3 dc) repeat sequence in parentheses 3 times. Ch 2, sl st to join to beginning of round.

Work several slip stitches so your next round can start in a ch-2 space.

Round 2: Ch 3 – this counts as the first dc st. 2 dc, ch 2, 3 dc in same space, (ch 2, 3 dc in next space, ch 2, 3 dc in same space) repeat sequence in parentheses 3 times. Ch 2, sl st to join to beginning of round.

Work several slip stitches until you get to the corner of the next ch-2 space.

Round 3: Work 1 sc into corner space, work 1 sc into each of the next 3 dc sts, work 1 or 2 sc in the ch-2 space, (see note below) work 1 sc into each of the next 3 dc sts, work 1 sc into ch-2 corner space, ch 2 to form corner. Repeat this entire sequence three more times for the remaining three sides of the square. Then ch 2 for corner and join with a sl st to the beginning of the round.

Note: In the sample, I only worked 1 sc st into the center ch-2 spaces. I did it that way because I wanted my square to fit snugly over my block, and that was the easiest way of making the whole square the right size for my particular project. If you plan to make a big square, the proportions will turn out better if you work 2 sc in the ch-2 spaces, as I did in this rainbow granny square pattern, which has 13 rounds.

Round 4: Sc in each sc; when you get to the corners, work 1 sc in each ch-2 corner space, ch 2, work another sc in same corner space, then continue working sc. At the end of the round, join with a sl st.

At this point, my sample square was the right size, so I stopped here. If you need a bigger square, repeat row 4 as many times as you need to.

Next Round: Using the accent color, work 1 sl st in each stitch, all the way around.

Begin the Sides of the Box Shape:

The sides are all worked in straight rows of sc. For the first row, for each sc st you’re going to work through three loops total: work through one loop of the sl st from your previous round, plus the two loops below it from the round before that. (See photo.) This will create a sturdy base that is also decorative. Work all the way across one side of your square, then ch 1, turn, and work back across.

Continue working rows of sc until the side of your box is the desired height. Be sure to jot down the number of rows you worked, because you will need to make 3 more sides identical to that one.

Don’t cut the yarn. Work back down the side of the piece you just made, crocheting one slip stitch per row. Later, these slip stitches will be used as guides for whipstitching the box sides together. Work slip stitches on the other edge too. Be sure to work an identical number of slip stitches on all your edges.

Make three more box sides just like that one.

Weave in all the loose ends.

Sewing the Box Sides Together:

Using a tapestry needle and your accent color, whip stitch the sides of each piece together, working through both loops of the slip stitches you crocheted.

Using your accent color, crochet one additional row of slip stip stitches all the way around the upper edge of the box.

Insert the floral foam inside the box, arranging it so that the corners of the crocheted piece match up with the corners of the foam.

Now you can use it in the project of your choice. If you’re not sure what to do with this box, I have some craft project ideas for you:

I am sure you can think of more great ideas for using this pattern. I have a few more ideas for using it too, but I haven't had a chance to try them yet.
