I remember some time ago one of the members here suggested a curtain material that was in Michael Guineys and very cheap.I bought some white, red and black and they work fine as backdrops and I think the whole lot cost me €50 ..See my favorite pic of 2007 where the white one was used. I will see if i can find the thread and post it here later.
