Actually kind of a fun project! Kinda like a jigsaw puzzle and trying to make all the pieces fit. Again, make patterns and use heavy duty scissors. These are what I used, I have several pairs for various things, I once cut a penny in half just to see how tough they were, worked! If you don't want to order from Amazon you can get them at Harbor Freight.
