There's a woman in my guild that uses strips to create blocks in a circular pattern and the finished width of the strips are only about 1/16th of an inch wide. Yes, that's 1/16th of an inch. So the strips she uses are about 1/2 in wide and then she cuts down the seam allowance to reduce bulk as well. She calls the scraps "Kibbles and Bits" that she uses. Nothing is too small for her.
