Step 1: Materials
-Pencil to mark off fold-lines
-Glue: I would recommend some sort of craft adhesive like E6000 perhaps. I used EXTREME REPAIR glue by LePage 'cause it dries clear, has a nice texture to it and is pretty much everything-proof (according to the package). If you can, use something that dries clear, 'cause unless you're really careful, It'll end up looking pretty messy.
