flowers and doo-hickys are glass bits and half-marbles. used clear GE II 100% Silicone Caulk (indoor/outdoor for window & door). think any clear caulk for exterior use would do. used an old toothbrush to stipple it on the glass, then pressed glass bits and marbles down on top of it. a small section at a time. forums2.gardenweb.com
