This is a pre-made 100% cotton denim backpack that I have unpicked and added patchwork using Moda "Frankie" fabric.  The lining has 2 inner pockets and the outer rear pocket has a snap closing on it so you can put your keys or phone in for quick access.  It's a beautiful thick quality denim with cotton webbing straps.  Measures 14x18"

Handwash in cold water and do not tumble dry.
