You can also put two of them right sides together, draw a line corner to corner and sew a 1/4" on either side from the line..cut on the line and you have (2) 1/2 square triangles.
You can also sew two of them together and then cut them in half long ways...and you will have multi colored rectangles..
You can sew sashes around them and make a cute scrap quilt...
You will get many suggestions :wink: try googling charm square quilts, and see what patterns come up too!
