Hi all, I'm in the process of researching best backdrops for studio work. I have used muslin and clothed backgrounds in the past but they are hard to work with because they crease and crinkled. It is a nightmare to get them smooth. I'm looking at paper backgrounds and I have a few questions. Are they reusable (ie re-rolled?) Are they the best solution for a smooth seemless background? Where is the best place to purchase them, or is the paper the same generically? Many thanks.
