The bag itself is extremely simple, so I'll spare you pics of the inside. It is made of medium weight cotton; the side seams are turned and stitched, the bottom seam is a french seam, and the seams that make the bottom square are Hong Kong seams.
I made the stencil from freezer paper. Man, I heart freezer paper.
The straps are made from a belt I really like but never wore.
