I made 3 g-boys (at the time, 2 yrs ago, they were 8, 3, 2 yrs) I Spy quilts--just a simple block with sashing and borders. I let each one pick out the colors for sashing & borders (2 colors each quilt) and used the same ISpy blocks (had collected from guild members plus a layer cut from Mo.Star for I Spy). All the same patterns, but different colors.
