Not sure if I could do a picture tutorial but did find some tutorials. I did find this company who sell these plastic looms that look about the same. Scroll down a little to see it.

Here's a pretty good tutorial on how to make them. My loom's nails are closer together than on the video, thus making for tighter pads. I try to put 4 or 5 yarn layers on mine to give the pads the thickness that I like. I also cut my yarn off where it loops around the nails instead of slipping them off (thus leaving little loops around the edges).
