So last week I made the Arizona flag out of Xpac and made a framebag out of it. I took a bunch of pictures of the construction, and wrote it up in a blog post. I forgot to take photos of some stuff, and a lot of it's specific to the AZ flag part of it. But there's still some useful info in there for those who want to make their own framebag.
