Who was it who suggested using the little, vinyl reinforcement rings instead of my trusty pieces of plastic packaging tape to reinforce the shroud line attachment points on plastic parachutes?
Whoever you are, I got some of the vinyl reinforcement rings. We are going to make two parachutes and do a head to head test!

For the record, these are the white, plastic, vinyl-type reinforcement rings (Avery item number 5729) not the paper kind of reinforcement rings. The paper kind seem quite fragile to me.
