I have used some folded blocks in quilts. It is very important to cut the fabric square EXACT and it helps me when I starch the square. Where you can fold a small piece of paper, it requires a larger piece of fabric because the fabric is thicker and has more give. If you want to fold a chicken, just try it. Follow the same sequence as with the paper. When it gets tricky, I often hold the pattern together with pins til the next fold.
