Do-it-yourself headphone case. Granny square

Headphone cases get scratched with frequent use and soon lose their original appearance. To keep your headphones looking like new, you need a case.

By the way, if you've held a hook in your hands at least once in your life, you won't have any trouble tying one yourself. And the granny square, the remnants of yarn, and a hook will help you with this.
We will now figure out how to crochet a granny square.

We need:

• leftover yarn,
• a suitable hook for it,
• scissors.

Symbols:

• CH – chain stitch;
• DC – double crochet;
• SS – slip stitch.

Pick up 4 ch and join them in a circle with ss. 

Row 1 - 3 ch, 2 dc, 2 ch, 3 dc, 2 ch, 3 dc, 2 ch, 3 dc, 1 ch, yarn over, in the 3rd ch of the beginning of the row we insert the hook, take out the loop and make all the loops on the hook. In fact, we have made a half double crochet and joined the row into a circle

Row 2 - 3 ch, under the half double crochet of the lower row 2 dc, 1 dc, (3 dc, 2 ch, 3 dc) under the arch of 2 ch, 1 ch, *(3 dc, 2 ch, 3 dc) under the arch of 2 ch, 1 ch* repeat 3 times, join in a circle with a half double crochet in the 3rd ch of the beginning of the row

Row 3 - 3 ch, under the half doble crochet of the lower row 2 dc, 1 ch, *3 dc under 1 ch of the lower row, 1 ch, (3 dc, 2 ch, 3 dc) under the arch of 2 ch, 1 ch* repeat 3 times. 3 Dc under 1 ch of the lower row, 1 ch. Join in a circle with a half doble crochet in the 3rd ch of the beginning of the row.

Then continue crocheting. The number of rows depends on the thickness of the yarn and the size of the hook. In the corners, we make (3 dc, 2 ch, 3 dc). Between the corners, on each side, 3 dc under ch.
Crochet 2 pieces. Join the 3 sides with ss for the inner half loops. From above, we also go in a circle with ss. Make a tie and pull it along the top.

By the way, such cases are suitable not only for headphones, but also, for example, for a mirror and lipstick.
