I guess I'm still catching up on some of the things here. WOW - That is a lot of clay!!! I have done something similar with my failed attempts at making some canes - and then I made some really cute little trees, and other things - I also dusted some of it with a pigment and then stamped them - they made great gift tags, and mini ornaments I like the idea of using them as little thank you tags too.
I have a bunch of clay still - well ok I don't have a bunch compared to what you have, but I think this will help with some ideas of what to use it for.
Those house canes are soooo cool!
