My thinking was a fitted sheet but with the quilted look. So it would have to be tight. Just not sure if that is realistic. I still have not done a bunch of quilts yet.
those talking about tummy time quilts. Bot sure if it's the same thing or not. I have the tops to some small quilts made. I didn't do a specific size on them but I made them a bit to big for a baby so she can play on them but also cover up with them as toddler toddler, since you are not supposed to give them a blanket when they are little one's. (I assume that's the same thing basically) first time mom not very experienced other then babysitting just yet.
