I have a 28" Titan 2 and use Sure Cuts a Lot Pro 3. How exactly do I want to feed my 24" vinyl into my cutter? Directly in the middle so there are 2" on each side or as close to the 1" side of the cutter as possible? Additionally, where should I lay the design out in SCALP? Bottom right? Leave an inch or two? It seems that I can't get this down and end up wasting extra vinyl on the sides of my designs.
