Thanks everyone. Believe it or not, my Dahlia is cut from a single piece of fabric, that sure saved a lot of time trying to decide on colors, fabrics etc. I think I will unfold one of the sections and try the advice given. I did use a ruler when I layered the fabrics but not when I folded them. It is thick and heavy. I can understand wanting to trim some of it out before using it in a quilt. It was fun!!
