Perforating Vinyl Yes, This can be a tedious process! This is what we've always done. We create a template out of clear rear plastic window curtain with all the holes correctly marked and punched thru. Cut a piece of black waterproof panel board to the same design and size ,then split in half. Glue your finish vinyl onto the split black water proof panel board. ( The split board gives strength to the vinyl but still allows to punch thru easily) Mist glue on only the template plastic, place on top of the vinyl/panel board piece. ( The misted glue allows the template to lightly stick in place) Then mark all the holes with a china marker. Lay onto a flat cutting board and punch away.
