9 Patch Block Swap

I was asked to join a 9 patch block swap by my Dyehard friend, Ann.  She's been swapping scrappy blocks with friends for a number of years.  I said yes so each month I am making ten 6" finished blocks.  Two blocks go to each of the 5 participants with one block having light corners and one block having dark corners.  I've been busy and actually have made about 120 blocks so far.  Pictured is a sampling of the blocks
