For those who are curious about what my gessoing party produced here you go.
 
This what came out of the party. A stack of 38 freshly gessoed canvases, and canvas boards and a large dash of white gesso sloshed on a dark brown leather chair while making a video about assembly line gessoing for a fan.

@ Arline Ninke bBrber - I will put it up when I can get the thing converted to mp4 from AVI. The problem is I use Mac and I can't find a converter simple enough for this basically computer challenged person to use. But I am trying.
 
If you think that leather lets go of gesso let me tell you it does not. So, I now have a permanent reminder of my first 30 - 30.
