I am wanting to get a couple of backdrops to use in my portrait photography business but I'm not sure what is best. Should I go ahead and get 10x20? What is the best size? I want something portable and easy to use but I also want something big enough that if I ever need to use it for a family or group shot I won't have to purchase another one. Have you heard of Owen's Originals website? It seems to have some good prices. I probably will just get a black one and a white one to start out with. I prefer solid backgrounds for now. I'm not sure what the difference is between the regular muslin and the economy. The economy has the option to add 3" pockets. May be a dumb question but what is that for? Thanks for your help.
