These are two crocheted squares used as pockets for the skirt. With crocheted top of the same yarn it makes a lovely summer outfit.

The size of the pockets is 11 cm. I don’t know the exact kind of yarn, it had no label it is a cotton thread around 400 m in 100 gr.
The schema shows a fourth part of the pocket, same should be repeated three times more. Each row has its own colour. The circles in the last row mean a picot 3. The picots are made on every sixth chain, but only for three sides. The upper side of the pocket has no picots.
