I ended up cutting the template out of cardboard, then putting a piece of double sided tape on the bottom so it wouldn't slip. Used my rotary cutter and cut out all of the colours. As the two coloured pieces are mirror images, each time the fabric was folded, I got both of those templates out. (Sort of a two for one deal!) For better or worse, all of the coloured pieces are cut and it's on to the white pieces!
Thanks for all the tips!
Wish me luck.
