Thank you Kim, Debra and Jan. Here in Vt we grow rocks, at least thats how it seems.... every spring there are rocks where there were none the year before. Rocks can be painted in any style, I've seen them as plant markers, with garden quotes...pet prints, handprints of children...all kinds of fun ways to add inexpensive decoration to the garden. I have some dl's that fit a native american theme, thinking about adding some color with native american patterns to that area. Mosaic tile would be pretty done on rocks, haven't tried that yet.
I'm fascinated by the glass towers, glass flowers can't wait to see images! The crafty/garden art forum here is awesome, good place to get ideas and instructions.
