I'm desperate to find a specific polystyrene craft ball. It's of "medium density". The higher density that's out there now is too hard. I cut quite detailed designs into them and then stuff fabric into the slits. The result looks quilt like. The web has been frustrating to say the least. Most web pictures are hard to distinguish and just when I think I see what I'm looking for on an overseas craft supply, they don't ship to USA. Does anyone out there understand what I'm talking about?
