My "GG" (grandma), was a gifted glass artist. I learned many things from her, more than anyone can imagine.
She is a free Spirit now, but with me always, especially in my studio.
Playing with glass was my favorite pasttime with her, and she'd been fusing glass WAYYYYYYYYYY back in the day, before there were "rules".
Anyhow...whenever I had a great idea that I wasn't *quite* sure about, I'd run it past her. And do you know what she would tell me?
"It's your glass. It's your kiln. You won't hurt either of them. Go ahead and try it and we'll see what happens"SO...don't be chicken. Experiment. Try it out. Take a chance. Waste some time. Get creative. Play. Don't ask first, because someone will just say "OMG NO, you can't DO that!" All of these *rules* cause everything to look exactly like everything else. Fusing is MUCH more than sandwiching a piece of dicro between 2 pieces of glass.

Don't listen to the nay-sayers.
Do it anyhow, and see. I hear my GG's words every time I go to my studio.
If you have followed this advice, I'd love to see some of your unique, crazy stuff.
