For my daughter’s 3rd birth day we threw her a pirate themed party – and that required a pirate flag. The skull and crossbones shape is a hand drawn stencil applied to a standard black plastic tablecloth using doubled sided Scotch tape. The spray paint took well to the plastic sheet, bleed thru was minor around the stencile, over spray was moderate (windy day) and the double stick tape holding the stencil easily pulled off with the paper.
As a gaming aid, I can see a lot of uses for table mats created using this method. Imperial Eagles, cammo patterns, cobble stone streets – just about anything could be cut into a stencil and sprayed onto a plastic sheet.
