I don't know what it is about me and curtains. But I was playing today and came up with this:

1. Make a highrez blank image
2. Run the fibers filter (different settings make for different curtains)
3. Run Motion blur set to 90-degrees and at the highest setting
4. Click in the middle of the image with the Single Row Marquee tool.
5. Define a pattern from the selection and deselect
6. Fill from the pattern you just made
7. Duplicate the filled layer
8. Switch to the background layer and fill with a solid color
9. Set blending mode of duplicate layer to overlay

Here's what I got with a deep red color:

Looks great Doug, I'll have to play with this one a little.

Look good, thanks Doug.

I will be needing some backdrops for some images I'm manipulating. I have used your last curtain making tutorial many times and now I have another method.

You wouldn't have any suggestions as to how to get a bottom edge on them, as if they really were a curtain backdrop that reached the floor in a studio setting.

This obviously needs some refinement, but here's what I did:

1. Saved a desaturated version as a PSD file
2. Selected the bottom of the color version and filled with white (black would probably look better, but I could also see transparency and a duplicate version colorshifted to gold so that it looked like a gold border)
3. Ran Displace filter, horizontal 0, vertical -10, repeat edge pixels, and used the saved desaturated PSD as the dmap
