I bought too much fabric, so I made a bag with my specialty, handmade crafts. It can hold two file cases. It can be folded and put into a bag, so I haven't used any stiffening material. However, it has a lining, so it's sturdy. It's convenient for work, school events, circulating documents, quick shopping trips, etc. It will be shipped via Nekopos in a Kakuni (size 2) envelope. Size: Approximately 35cm tall, 31cm wide.
