I'd like to ask some advice if I may?

I am a LONG time user of PSP and have Photoshop Cs4 but don't know it as well as I should and I tend to try and gravitate back to my familiar PSP.

I do some texturing for clothing and have been buying some of the brush sets here with the folds to add realism to your fabric.  But I am having a hard time trying to figure out the best way to use them. I try multiply and it's too dark. I try screen and sometimes it doesn't show up.

Is there some trick in using brushes to accent the material and have it look right? I even wondered whether you are supposed to use a coloured brush rather than a grey one.

I would love a tip to get me started and perhaps encourage me more to use CS4.

Thanks for any help offered.
