I always mix it makes it fun to be able to have different prints to look at.For instance, if you only have one of each, would you use the pirata wallet with an inferno pouch inside a paradiso bag? I would love to get one of those little pouches to put the little stuff like my makeup and hairbrush, etc., but I am thinking I might want to get it in a print I don't have. Is it done or is it a no-no?
