I went through about 20 different textures before I settled on that one (can't think of the name right off the top of my head. The shadow is actually the result of me duplicating a layer and turning down the opacity on the original layer so that a tinsy-tiny shadow showed up. I'm not sure I could do it again if I tried. I should've written down my steps. I guess I'll chalk it up to beginners luck, because so far I haven't been able to perfectly reproduce it on other things. :\
