Light and Dark about 1 1/4"finished tumblers.  You will get 50 different  lights and 50 different darks in each pack. that will make you a little 10" x 12"  quilt ( as shown there are 90 pieces) or alternate light and dark and you can use 99 of the 100 pieces.  I wanted to do something different by having darks in the middle surrounded by lights. $14.00 and they are all accurately cut and ready to sew.
