I think the mattress pad will be okay. IF the velour is of a color that doesn't show through, and the weave of the quilt fabric is tight enough, I might try the velour. I think I would try a small piece and put it together in a small doll blanket size, finish it and launder it and see what happens! If you like the results, go for it. You won't know until you try it! :lol:
