Cert Badge Material

[shui054]

Hey guys, I'm the safety captain on Team 1257 Parallel Universe. There isn't a forum dedicated to safety, so I'm just posting in the general forum (sorry!).

I'm making certification badges for all the members of our team, so we (members and mentors) can know for example who is certified in what (e.g. use of electronics tools). It'll be helpful for everyone to learn from each other and for the captains of each subteam.

I've attached a draft I drew up before the school year ended, but I'd like to know your recommendation as to what would be the best material to make the badges out of. I have no expertise in this area at all and would really appreciate your help.

Thanks!
