Japanese inspired drawstring bags

Using a combination of ideas from Kumiko Sudo's book Omiyage and a pattern from kimoYES I've been playing around with scraps of Liberty fabric to try my hand at making drawstring bags with a Japanese influence. The construction is 'patchwork meets origami' with triangles and rectangles coming together to make a square-based bag. Casings are added to the top for the drawstrings. The lining is a rectangle sewn with a series of darts to shape the base. Once I got the hang of putting each piece together (although it did take a few tries!!), it was a straightforward process.
