I often save up used dryer sheets to make sew and flip crazy blocks. I can get a six inch block out of one. I have a tub where I save them. I decided when I get 144 I will sew them up into a quilt. I am up to 100. I also use the dryer sheets to make cloth books for babies, it is nice to include a "first book" along with a quilt.
Also when I use paper for this type of block, you do not have to remove it. If you are making a scrappy quilt, just leave it in and it will melt away in the first wash. The first quilt I ever made was a crazy scrap done with newspaper. The paper was not removed and washed out with the first laundry. That was forty plus years ago, and the washer was an old wringer. I believe between me and the kids and the wringer that quilt was just used up into a ball of threads long ago.
