then start in the center and work out side to side, top to bottom...you do not need alot of quilting, just a few lines down and a few across and it's done and ready for binding. fleece is also a good choice if going to tie your quilt.
i'm sad so many people say...don't use fleece...it makes wonderful quilts!
