My I Spy quilt is a WIP and is EPP. It is a great take along project. I use whatever scrap pieces of paper I can. I print my own hex's and cut them out. Another great project when in Dr's office, watching TV, sick, etc. I also have a GFG WIP going very slowly. Doing that one in 30's repro.
I use this site to print my hex's.

I have a method that I use to make better use of the paper so I don't waste so much. I print out the size I need (or use the Enlarge/Decrease button on the printer) to tweak it to size, then I print out enough copies to cut up and pace on one sheet to fill that sheet as much as possible, then make as many copies as I deem necessary. I keep teh original copy in a master file with the size of block, amount/percent increased/decreased to, and which project I am using it on. I have a ruler nearby and measure, measure, measure before cutting into fabric.
Lost yet? Not as complicated as it sounds when you get a method that works. Use mostly scrap paper and doesn't use much ink to print.
