I have made several "I spy" quilts. I just started collecting. I bought 1/4 yards at JoAnn's or bought them from fat quarter spots on Ebay. I took the time to fussy cut them into 5" and 6" squares. I used 100 different blocks that were sashed in black. It's time consuming but probably the most used quilts I have ever made. Every time I see my Grand nieces they run for their quilt and we play I Spy...priceless.
