trimmers have been using this foam for years...it was mainly used for padding vinyl tops.i've never seen it available to the general public,so u will have to buy it from a trim shop.glue it to the surface(both sides/let it dry first).u can precut designs then glue or work fast,let glue set up just a bit then cut design with razor knife& remove.then u must reglue padded surface&fabric...tweed works best,leather is better,standard 28 oz. vinyl doesn't work well at all!that is why the ultra leathers are expensive,they react similar to leather& they're washable&fire retardant(used mainly in aircraft).
