I just used 2 1/2 in. strips of fabric left over from Ben's quit, pieced them together then used the decorative stitches on my machine to "quilt" the layers together. Some in red, some in blue. Then I bound it with some bias binding (store bought of course).
It's just big enough for a pack of travel wipe and a couple diapers. This will go in his pre-pre-school backpack, and with us on the road when we just don't need the whole bag.
