I made an 'eye spy' quilt for my grandson. I bought several collections of squares on ebay. I think they were
4.5, 5 and 9 inches. I trimmed the big ones. I did not want to buy quarter yards of 400 different fabrics, although I did have a few novelty fabrics in my stash. We did have to buy a 'Woody and Buzz' fabric and a 'Thomas' fabric because we couldn't do without those.
