Tutorial: How to Sew a Fabric Box

The other day, I decided to make a little fabric box for Bun's dresser, to keep the baby socks tidy. When I went looking for fabric box tutorials, I found a ones that used felt, or quilting, or even some sort of plastic inserts. There were lots of different styles: another felt fabric box, a simple fabric box, another fabric box. But none were quite what I wanted, so I decided to make something up.

I wanted to make one using just interfacing (since it's what I had on hand) and I liked the look of this fabric box.  I decided to take pictures of the process and write up what worked for me. This will make a 5x5" box.

Materials:

    5 squares outer fabric (5.5 x 5.5 inches each)
    5 squares lining fabric (5.5 x 5.5 inches each)
    10 squares interfacing (5 x 5 inches each)
    Fabric for binding the edge (3 x 25 inches)

I mostly used heavier weight fabrics and interfacing for this project. My binding fabric was just regular quilting cotton, though. You may only want one layer of interfacing if the kind you're working with is very thick. You can adjust the size of your box as you like, just make sure the interfacing does not include seam allowance.

Step 1: Iron interfacing to fabric squares

Iron the interfacing squares to the wrong side of all of your fabric squares. Make sure that you've got them centered, with a 1/4" seam allowance all the way around. If you're only using one layer of interfacing, I'd use it on the outer fabric, rather than the lining.

Step 2: Start sewing lining

Lay out your lining pieces in a plus symbol. The center piece will be the inside bottom of your box. If the fabric has a directional pattern, sort out how you want the squares oriented. Next, pin the lower piece to the center piece, right sides together.

Now sew that one seam, following the edge of the interfacing. Be sure to start 1/4" in and leave the last 1/4" un-sewn, so your stitches should just be alongside the interfacing. Backstitch at the start and end to secure.

Repeat for the upper square, attaching it to the middle square, so you have a strip of three. Press the seams flat (not open!), facing out from the middle square.

Step 3: Connect the side squares to create plus shape

In the same manner as above, sew the remaining two squares to the middle square, to create the plus shape you laid out. As before, do not sew through the seam allowance. When you're done, the middle square of interfacing should be outlined with your stitching. Press the new seams flat, facing out from the middle square.

Step 4: Sew up the sides of the lining

Pick any two of the side squares and lift them up, to begin creating the box shape. Pin them together and sew the seams as before, just following alongside the interfacing, and leaving the 1/4" at the start and end free. I find it easier to sew if I also pin the top edges, so it lays flat. I make sure to use a different pin colour so that I don't accidentally sew that side together! Repeat this for all four sides of the box.

Step 5: Sew outer box and trim seams

Sew the outer squares together in the exact same manner. I trimmed the seams of the lining with pinking shears and trimmed the bottom corners of both the lining and the outer box to make them fit together more easily.

Step 6: Insert lining into outer fabric box

Flip your outer fabric box so that the right side is facing out. Once it was flipped, I ironed a bit along the seams to try to crisp up the square shape. Stuff your lining (with right side still facing in) into the box and fuss with it until the corners are lined up. It will probably still look rippled, like mine did, so pin it all together, then sew a seam along the top edge to hold it snug (this will get covered by the binding in the next step).

Step 7: Attach binding

Iron your strip of binding fabric in half lengthwise, then pin it to the upper edge of your box (with the fold along the bottom).  I found I didn't have enough space along the side to do the joining part. Instead, I ironed back one raw edge into the inside of the binding strip, and just tucked the other end of the binding inside that. I then sewed around the whole top edge of the box, using a 1/2" seam.

Step 8: Hand-stitch binding on the inside

Fold your binding over into the inside of the box, pin it in place, and hand-stitch it down using a ladder stitch. And then you should have a pretty little fabric caddy for storing small odds and ends!
