This year end project (spring 2013) was a big experiment. I had never worked with coils before so I really didn't know how they would turn out.
I found fabulous examples from http://www.pinterest.com/pin/86835099038889385/
The whole process took longer than I had planned. However, I don't think I would change anything other then maybe some prequel exercises. And make sure that the glazes are not burning to hot. There were some minor issues with the heat of the kiln.
Also, I was pleased with the results of having them incorporate a theme, but with time permitted I would get them to expand on their ideas, less flat and more 3 dimensional.
