It is very interesting technique to make Curtain in Photoshop. Photoshop CS is required to make curtains, because WARP command required to do so. So I’m going to tell you step by step.

3. Now run the command Filter >> Render >> Fibers and give the following values in relevant boxes.
4. Now run the command Filter >> Blur >> Gaussian Blur and adjust the blur setting, here I’m giving 2.9.
5. Now run the command Filter >> Blur >> Motion Blur and give the following value (you can give according to your desire).
6. Now run the command Edit >> Transform >> Warp command. Some kind of Grid will come,
use top 2 and bottom 2 center nodes first and move them down and then by using other nodes make the following shape and then press <Enter> key.
