Sconce

I've decided to make a sconce. I watched Ty Pennington on Oprah make a very cool sconce out of a piece of wood and an uplight last season. I use to really like Ty, back when he used his inside voice.

I plan to develope the concept into something with clay. I want to acheive the look of fused glass, but without the super bright colors. I'm not quite sure how I will make it work. I thought about magic mesh, but I really don't want the grid look. What is clear, plyable and heat resistant? And of course affordable?
