Sometimes when I am cutting something out I want to get the prettiest/snazziest piece of vinyl tarp for the job.
The cutter I use for cutting vinyl has a support sheet that is either 12X12" or 12X24". I built a template for laying on top of the vinyl to get the exact dimensions for the cutting sheet. The cutaway portals are so I can see the look of the underlying vinyl that I am cutting. It is from a recycled coroplast campaign sign. Coroplast is like corrugated cardboard but it is made out of plastic, #5 if I recall correctly.
I added a couple of sandbag-style weights to keep the template in place while I am cutting. Genius!
