I made a book bag, gym clothes bag, shoe bag, and lunch bag using cute light blue bear and rabbit patterned fabric. The book bag has a quilted lining. The gym clothes bag has no lining and has a gusset. The gusset is a folded gusset, so it becomes flat when not in use. The shoe bag has a lining and a gusset. The lunch bag has no lining and no gusset. These are handmade items by an amateur. Please understand this before purchasing. Book bag: 39cm wide x 29cm long x 5cm gusset Gym clothes bag: 28cm wide x 32.5cm long x 6cm gusset Shoe bag: 19cm wide x 25cm long x 4cm gusset Lunch bag: 19cm wide x 24cm long
