25th March 2014: Buckles added! Since I cannot make them of metal or plastic, I've come up with a way to make them, hopefully, sturdy. I cut a basic shape from cardboard, and then put silver fabric over the top, sewing it to the cardboard. For the vertical strap buckles, I've sewn the buckles to the webbing itself. Only done two so far, so we'll see what happens with the rest.
