I really love these linen bento bags. They're great for farmers markets and lunches. I also really enjoy the challenge of looking at something and determining the construction. I could tell these were simple in that lovely origami and inside out kind of way that sewing often is — but it took a bit more experimenting and researching to figure this out.
As far as I can tell, there isn't a really good tutorial (I found a couple confusing and incomplete ones) online for making these. I'm happy then to get this out there! All the steps, photos and diagrams after the jump.
