I know I am not the first, but I thought that I would share what I did. I used the plastic from a DVD case, a lighter to form it, and a glue gun to set everything in place. You can also see the slightly modified bookmark. I hated how it flapped around, so I slipped on some shrink tube, tied a knot, trimmed the excess, and voila!
And of course it’s not complete without a WESBC sticker on it!
