The borders are finally on! The top and bottom borders are 16 inches wide and the side borders are 18 inches wide to make the entire quilt measure 96x85 inches - large enough for a full-sized bed. In the photo, the top border is folded over to keep the quilt top from touching the floor. My design wall isn't tall enough for this quilt.
Now I have to figure out what to quilt on those wide borders :D
