When I do put together a "practice piece" I will keep using it again and again, changing out the thread color to see what I am doing. I have also put a new piece of fabric on the top and bottom and practiced again when it got too full to see what I was doing. I use old fabrics that I found cheap, old sheets, muslin etc, but have warm and natural in my "sandwich" cause that's what I use in my quilts and I want it to "feel" the same.
