I do a lot of paper piecing so it's worth it to me to use the best pp paper. I use vellum lightweight translucent for large pieces. For a lot of pieces in one block I use Stable Stuff that I leave in, or the water solvable paper. All three are printable. My first paper piecing I used printer paper and almost threw the blocks away the paper removing was so tedious. I knew I'd never do that again. My frustration level is too low for that tedious work.
