I've got two boys, and now that daddy isn't around to carry one of the diaper bag backpacks, I'm going back to one large tote.
But I needed cases because I do not like Noah and Tristen's diapers mixing around everywhere and having to dig for the right size. :)
There are probably easier, more efficient ways to make one, but I winged it and I like how it turned out. : )
(ignore my reflection in the glass >_<)
