I use Photo Impact 8.5, and it came with the Xenoflex 2 filters. There is a filter within the set that makes things look crumpled. The filters can be purchased separately and are compatible with many graphics programs, but I don't know how much they cost.

Although I haven't done this, you could try using the texturizer (or similar feature) in your software. Most allow you to load your own texture. To try this:

-Photograph or scan a piece of crumpled paper
-Convert the image to grayscale
-Save it as a jpg or your software's native format
-Add it to your texturizer following the directions for your software
-Apply the texture to the paper you want to crinkle

Have fun!
