Our videos were done by Beth at Blue Mountain Handcrafts who beta tested and put the tools through their paces to see what they could do....and then some. 
Recently she made the videos private and we can no longer access them.... I am currently trying to resolve this.    There are some videos here by Reservoir Fibers.  You will also find quite a few other videos on youtube  if you just search Fancy Kitty drum carder/ fancy kitty picker/ fancy kitty tumbler/ fancy kitty blending board etc.    Thank you for your interest.

Videos are grouped in categories by the tool used in the video.

Drum Carders
Blending Boards
Pickers & Tumbler
