Moop has been designing and hand-making canvas and waxed canvas bags in Pennsylvania since 2007. There are many styles of bags; I am partial to the shopper.
It is an open tote. If closed tops are more your bag, there is the letter bag and a bunch of other styles.
Moop also makes backpacks, messenger bags and a variety of purses and clutches, all made in the usa.
My favorite thing about their site is that they illustrate what will fit in the bags with line drawings.
