{S-Scale List} wallboard mud

[Alex Binkley]

Hi:
 I have been gifted with a large partly used pail of wall board mud and 
wondering about what to do with it.
 One idea is to create blobs of it, let dry and then paint in rock colors. Or 
break up the blobs to create small rock and boulders and colour.
 Any benefit to this. Better idea with what do with pail. It would be worth 
keeping even if the content is useless.
cheers
