I made a bag from indigo-dyed fabric with a stencil pattern. Medium-weight interfacing is applied to the entire outer fabric. Furthermore, the bottom and opening have double interfacing. It's firm and sturdy. Dimensions: Opening 38 cm Height 26 cm Bottom 30 x 8 cm Inside, there are two pockets. The opening has a facing and a zipper base. It's long enough to be worn over the shoulder.
