A tip my mentor ( long time quilter) has done that I think is brilliant. She used batting to make a design wall, put it up on a wall with a crown molding piece, and the batting hangs down to the floor, quilt pieces stick without pinning , to be moved around to find how you want them. Lots easier than crawling on the floor, and you can cross the room to get a better view.
also my view on striving for perfection, won't happen from this girl, but I always try to make this project a little better than the last, and learn from your mistakes.
