Hi all, This is probably a retread, but I gotta ask: I need to work out a bit on my portrait skills and haven't a dime to spend, specifically on backdrops. Muslins run over my range. Sheets, on the other hand... Well, I know some people have used them, so I wanted to ask about your experiences. 1000 thread count egyptian cotton sheets are as much as a muslin and too dang shiny. What about flannel? Maybe el-cheap-o Wal-Mart 120 TC grey ones? Any feedback is welcome... Tx!
