Here's a thought...probably only good for scrappy, string. Example: 5x5 block. Paper cut to that size, but when you finish block and trim fabric, trim to 5 1/2 x 5 1/2... Then you can leave paper in for stability, but the seam allwanes are paper free...I use old phone books and I get prospectuses from investments regularly...don't read them, but paper is thin enough to be used.
