This is a template for cutting 8" squares, typically out of patterned papers for Origami where you would like the design to aligned in a specific fashion.There are 2 spot colors defined in the file - Cut (Red) and Etch (Blue).I have found that 1/8" frosted acrylic works very well. I recommend the etch be on the frosted side and that the template is used frosted side down. This results in the best visibility of the aligning grid.
