Got some furry fabric, any tips on coloring, etc...

Got some fur fabric today from my local fabric store and cant wait to play around with it! I picked up two different fabrics, both about same height and fluffyness but different base coats. One is a little whiter than the other but look fine, but ill definately have to paint or die them or something. Any tips>>? Or other suggestions to help with realism? Thnks, Ben

I got some today as well and plan on experimenting with the techniques described by Harold on his excellent web site http://www.pacificcoastairlinerr.com/fur_grass/
