I thought these didn't exist. The amount of times we wished we didn't have to line up, tape a mouse mat or coaster to paper and turn it over for pressing. Always a possibility the thing moves. With a heat plate on the bottom then you could have your artwork face up, still stick the item down (or in jig) and then move paper still face up into press. Or am I missing something?
