Two points:
1] I use 25% rag vellum for PP as it is easier to work with for me .... I bought a whole bunch from Office Depot. They also ship if needed.
2] If you know someone with an Electric Quilt program, they can make the block for you and print it out. Then you can copy that.
I have EQ if you need help and we can always e-mail, if you don't have someone close to do it for you.
