I made a book bag, gym clothes bag, shoe bag, and lunch bag using cute cloud and airplane patterned fabric. The book bag and shoe bag have lining and a gusset. The gym clothes bag has no lining and a folded gusset, so it can be flattened when not in use. The lunch bag has no lining and no gusset. These are handmade items by an amateur. Please understand this before purchasing.
