Mask 1 Tabs

You can use these tabs to wrap a rubber band or something similar around the mask without having to cut it. I created this specifically for the 116x123 mask, but I haven't had time yet to make ones that fit the rest, so you can easily do so by reducing the dimensions by just a few millimeters.
