I make a sleeve for the Bag-e-bottoms. I like the sleeve because it covers the seam at the bottom of the bag. Even though there are no raw edges, I still think it looks better with the seam covered. Then you can stick anything you want in the sleeve - cardboard, Timtex, plastic canvas, etc., etc. The acrylic Bag-e-bottoms slide out when you want to wash your bag.
