The stitching style called "Crazy quilting" is a technique of assembling flaps of fabrics of completely different shapes and colors in a semi-random fashion, forming beautiful, intriguing and crazy patterns. If you have too many pieces of cloth left, it is possible to make a pillow in this style. They are easy to make because there is no wrong way to assemble the pieces of fabric. Choose the flaps you will use. If they match something in the room, that's a bonus. Each side of the pillow can be completely different, and you can be as creative as you want.
1. Put the pieces of fabric in any way you like. Some people are sewing "in the wind" and are putting the pieces on the side that they think is best. Do it your way, whatever it is. There is no way to err; use your creativity.
2. Sew the cloths with the right side out so that the seams are hidden when finished. Continue until you reach the desired size for your pillow.
