I've never used www.lemondropstop.com to purchase backdrops, but they're having a buy 3, get 1 free sale today, so I'm tempted. They have a lot of really cute stuff, but they have 3 different materials, poly-paper being the cheapest, vinyl in the middle, and canvas as the most expensive. I don't have any backdrops (I have just improvised with sheets or large fleece blankets)... But I'd love to have some, as I think I might get a backdrop stand for my birthday. So anyway, I was just looking at opinions if any of you have happened to use this site before.
