There is a teflon mat called a "supreme slider" that I use when FMQ on my domestic machine. It reduces the friction of the quilt on the sewing machine bed. Now I won't quilt without it - it makes that much difference.
I pin baste. That way I can adjust it a bit if one layer pulls in more than the other. With regular basting, I don't have that flexibility. I don't use basting spray.
Good luck with your quilting!
