just finished this today....it's a custom order for Shin in Japan.
He chose the fabrics, and the dimensions of the bag - all via emails!
The exterior is an indigo blue corduroy, with a very graphic lining fabric.
I really love how this came out, especially the contrast of the interior and exterior. Think it's got very clean lines, and has a pretty sharp look about it. Quite manly now, don't you think?
