The project that I used it for was my forest and thought I would share. Pines are made using this tutorial. I followed it to make the armature and I used putty to make the bottom of the trunk. Once the putty was set I spray painted them black, used spray adhesive to attach the flock and finished off with clear plasti-dip spray rubber. The birch were made using my tutorial for Birch Trees. I added rubberized horse hair using fantastic elastic. Once this was set I used the spray adhesive and plasti dip again when I added the flocking. Bases are from 4 Ground. I did a total of ten bases with twenty four removable tree bases.
Here are the photos.
Here is the difference between the homemade rubberized horse hair and the purchased.
I tried this before without the plasti dip and the trees shed quite a bit.
I had just finished when one of the guys in my game group asked me to base his trees too.
