Made this large 20" x 15" (Approx. size) beach bag, from 5" Black and White charm paks, getting ready for the summer and travelling. I covered a fitted piece of plexi-glass with the bamboo material, for the bottom of the bag, which is removable for washing. Used Iron on Batting and top stitched around each square, so it will retain its shape. It will hold a couple of large beach towels, swim wear, flip flops, snacks, drinks and lotions for two people.
