These are really great. Did you have to do any burning around the points where dog meets floor, or is the material really THAT non-reflective?

B&H has a roll of black Vinyl that I'm thinking about getting as a companion to my white Vinyl. It's supposed to be non-reflective too.

How wide have you been able to find the velvet? That's been my biggest setback to DIY backdrops. It's hard to find material wide enough.
