I used my scraps and cut into 2 1/2" strips. Did not count how many, sewed together until the pile was as high as my chair seat. Some of the scraps were short and some longer than the 40" requirement. Found the 2 ends and began sewing together. Folded the long snake, it went from one end of the room to the other, about 60'. Folded and did it again. Over and over, when the the quilt was the size I wanted I added boarders. It became a queen size quilt. The fold will twist, so either un-sew or cut when you get to the end.
