Have started to think about White, the new baby show I will be working on. At the New Vic the room I do the show in is separated by curtains and many of the children really enjoy them. A small boy loved turning in them the other day. A lot have enjoyed pushing them and the shapes they have created on the opposite side from them have been great 
I like the idea that you might be able to see through them at some point and had also been thinking about net curtain. Covered but seen. In but out. For a baby could be quite fascinating. Pretty horrible for us though...
