so tonight, with a spark of inspiration i built a prototype collar.....i'm sure that if i put my mind to it i could build a much nicer, better, more interesting one....but here is what it looks like:
it has some grommet tape at the back and laces together, making it adjustable....it was actually suprisingly easy to make...and with some snazzier fabric and maybe a bondage ring or something, it has major potential.
