Hi Rose,
I use zip ties to keep my wires neat and tidy. They have some sticky pads to keep them snug to the frame.
Also on your leaders I made some from thick ticking fabric from Joann's, the fabric has lines on it so it was easier to install on the frame as well as pin to. I also installed zippers to my leaders. But you still have to pin or baste your backing. I like zippers because I can take them on and off easily. Hope that helps!
