I made a tote bag (no gusset, with lining and inner pocket) using vibrant African print fabric ^_^ It's a size that easily fits A4 documents! African print fabric can feel a little thin when used for a single-layer tote bag, but adding lining makes it sturdy!! The inside uses navy blue cotton fabric. The inner pocket is made from the same African print fabric as the outside. How about using it as a main bag or a sub-bag?! The size is 35cm (height) x 33cm (width), with a handle length of 40cm.
