I made it up as a travel bag. The directions were pretty easy to follow, and it has lots of zippered compartments, places on the side for a water bottle (or baby bottle). It would work great for a baby tote, but not as a quilt storage bag (too many compartments). For that I think something simpler would be better. So it depends on what you're looking for.
