i have a hot laminater and simply put in one sheet with the design i wish to create the templat from in between the plastic sheets and then put the second plastic set on top that. pop into the card protector and laminate as normal they all fuse together and that way you get the thickness and can actually still cut out the shapes that you want.
store in zip lock bags for safe keeping with a printed copy of the original design for future referance
