I made this to go with the nursery bedding. It's a 6in+8in square cake frosted in buttercream, with fondant ruffles (and elephant in the 2nd picture). For the quilting, I used a regular diamond impression mat, then went over the whole thing again but moved the impression mat up about half an inch or so. The frosting kind of stuck to the impression mat (guess I didn't let it crust enough), but I thought it gave it a cool, more real look, so I didn't bother trying to change it.
