the quilt top is really "dark" boyish fabrics so there is no way for the fabric in the middle to show threw. and I actually did spray baste it. I do agree about the top sheets that you can buy for crib mattresses. but I understand why they don't because there would be a mom who would tuck her new born baby in the top sheet and it would end up dying for some reason. (not making light of sids or any form of a child dying) they say the only thing in a crib for the first 6 months should be just a baby. no blankets pillows or toys. not even the crib bumper. (they do make mesh bumpers that are supposed to be safe now.)
