Cathe

I find it more helpful to know the mattress size and then decide how far I want the quilt to extend and hang down on the sides. I actually prefer square quilts for my Full and Queen beds, because then they hang down on three sides (both sides and the foot of the bed) and I use pillow shams and cases with them. The chart assumes that for this type of quilt, you pull the top edge up to about 6" from the head of the mattress. I usually pull it all the way up.
