This challenge is to design a block (or blocks) using a geometric design (size: 6 or 9 or 13 in finished) that will show movement with the use of a "zinger" fabric (i.e.-stripes, wavy, or checkered fabric, etc.) Example — a star using one fabric that is a stripe and the way it is put in the block makes it look like it spins! Another example is a pinwheel or variation of winding way pattern. The more blocks you have, the more movement you will experience. This is also related to the size of the "zinger" fabric design, so you may have to experiment a bit for the best effect. Have fun!!!
Colors are your choice. But a bright fabric as a "zinger" works well!
