So many great observations and ideas here - thanks for sharing. I have a question for those of you who piece your backs. I have really struggled with keeping pieced backs on grain. I've done two - one like Julienm1's that was for me - it was my first pandemic quilt and I didn't have anything suitable for a backing, so I made a second quilt out of the stuff I'd used on the top and mashed them together. The other was to make up for fabric that wasn't wide enough for a backing. Both of them ended up being slightly off-kilter. Since I did stitch-in-the-ditch quilting, it's pretty obvious. So... any tips for making sure the backing is squared up to the top?
