What do we usually do after completing major projects? We're sorting through the leftovers, trying to come up with something new. I found some denim pieces: pieces of gray, green and blue. We look through them, where possible, we cut out details measuring 5 by 15 cm, taking into account the share. This block is most conveniently sewn on the base. I found a piece of adhesive non-woven fabric. On it, we will mark the auxiliary lines in the center, and then the angle of 90 °. Let's start with the bottom edge: first, we will close the corner, and then we will sew strips of fabric to it in turn.
