zip up hoodiesanyone here print on zip up hoodies and print over the zipper. my boss wants to get into it for all the band shit we do. i have done by routing a slot down the middle of the board and by using 2 pieces of rigid cardboard to elevate the sweater and leaving a slot down the middle. how do you do it? does someone make a system for it? i need to figure out the best way to do it. thanks!
