What about newsprint, you can go to your local newpaper and buy the end rolls for about a dollar and there's a lot on there. Just cut to size. If it doesn't tear easy, spray with a little water and try again. Plus it's wide enough that you can draw a larger pattern on it if you're doing a special center block.
