Except for the first experiment, I used Citadel's burnt grass flock:
http://www.amazon.com/gp/product/B002Q2 ... d_i=507846because I was buying some purity seal at a Gameworks Shop and just saw it there and picked one up. I looked online to see if it came in different colors, but can't seem to find anything
I got a huge disappointment 2 days ago when I received the flock samples from Don Jer. They were extremely fine which I think was a problem, but they arrived in small packs tightly clumped so I spent like an hour pulling the fibers apart only to have them tightly bunch up again after only 2 shakes of my flocker :/
I tried only using a pinch of fibers and tried using all the lengths, but the same thing keeps happening. Just one or 2 shakes and the fibers cling together into a tight ball.
Even if I can get them to work, I think I might prefer thicker fibers so I wrote back to them again to ask them if they have different thicknesses, but I also wrote to Cellusuede since they have a larger variety of types and thicknesses.
No word back from them yet though.
