Making Arlinn Kord's Shoulder Guard

This is basically what I was working on this past weekend.
I'm trying to put together 2 costumes in 2 weeks! (Gotta make dat Shadows Over Innistrad pre-release deadline.)
 This is probably one of the best cosplay piece I've done in a long time, but ti was also my first time working with vinyl! (So very expensive- thank you Jo-Ann's 40% off sale o.o )

If anyone is interested in how I put it together you can watch a video of the process here- www.youtube.com/watch?v=RKw2-H…

I wouldn't call it a "tutorial", since this was my first time making something like this and it is by no means perfect, but maybe it can help serve a jumping off point for other people!
