Rita, your quilt is fantastic and it looks like you will be able to enjoy it for the holidays!
As for the lines staying with pounce, Hancy's pounce pad instructions provide helpful hints, among them one that says that "if you have trouble with the chalk rubbing off the fabric too soon, spray the chalk outline lightly with an alcohol based aerosol hairspray, it will stay on until you wash it off." Of course, that only helps if you plan to wash your quilt, but certainly is a tip worth considering, especially since using the pounce pad is quicker than marking every line.
