For this project you are going to be using up some scrap fabric. (Most of us have scraps from other projects.)
Before we do any sewing we are going to play at the iron.
You will need your 4 small squares for this.
Step 1 - Fold square in half, diagonally and press flat.
Step 2 - Take left bottom corner to right bottom corner and press flat.
Repeat this for each windmill section.
