Cool curtains. Had a few minutes and did a quick try using an image of a piece of fabric, repeated gradient, distort brush and a quickie shadow. Not production quality but maybe I'll play with this again. I like the lighting effects and folds on the ones you guys did. Have to see what I can do with lighting in PSP though I suspect I'll just have to paint a dodge layer to lighten up the sections I wanted. Here it is about 10 minutes work in PSP and applied to a wall in 3DGS just to see what it could look like.
