This is a block swap quilt. A group of 10 people all made the same block, so each person keeps one of their own blocks and gives the other 9 to the others in the group. Once you get the ten blocks, you put it together as you wish. There was one common fabric in this block. You will note that it is 3 by 3, (9 blocks) and the tenth block has been cut in four to help in squaring of all the blocks.
This was made with an Amy Butler free pattern available on the web with Amy Butler fabrics.
