i desperatly wanted to make one with wheatgrass in it (a little stone temple or buddha amongst the grass sounded like a nice image) but i can't find wheatgrass anywhere!!! the herb idea is nice though. if only i could keep herbs alive
(i tried rosemary, because it's almost impossible to kill where i live in az and yep... i killed it)
aw. don't worry. actually, rosemary can be pretty tempermental. if you want to try growing herbs, dill is really easy (although it takes a while for the seeds to germinate) as are oregano and basil. i've been successful with the latter two every time i've tried.
