Place quilts face down for rolling, and then roll from the bottom up. Swimming noodles can easily be cut to fit. Just use an old kitchen knife. Note: I've used the noodles "as is" for years with nary a problem. If you're concerned about "off-gassing" you might consider covering the noodle with muslin.
I use selvedges torn from cottons for tying rolled quilts. These strips are also perfect for tying tomatoes in the garden!
