I found a bag with some half finished I Spy blocks. I think I started this top when I was looking for a pattern to use some strips leftover from cutting squares. The inspiration was from Bonnie Hunter's "Star Gazing" in her book Scraps & Shirttails. Spinning Stars is an easy peasy block and only needs 2.5 inch strips.
Here's a finished Spinning Star with 2.5 inch sashing. Doesn't it look great? And it's such an easy block.
