I have my backing and my top done. Here are a few questions though.

Everywhere I read it says to have your backing about 3-4" bigger all around due to shifting during quilting. I only have about 2" all around. Is that going to be a problem? Should I just pin extra pins or spray and pin?

Has anyone sandwiched in sections due to space issues? Like the top half and then move it to be able to pin the bottom half.

When you quilt, how do you start and stop? I mean are you supposed to back stitch to lock it? How do you keep the stitches from coming loose at the beginning and/or end.
