Have you checked out Moda Bake Shop? There are a lot of modern patterns there.
http://www.modabakeshop.com/ Have the parents look there and find one they like , then use their material. I don't think you could go wrong if they picked the pattern too. :D We all know how things change by the time more children come along ;) Me, first one, freak if toy fell on floor. Fourth one , brush it off, no sweat. :lol:
