I forgot to thank Courtney for her contribution. She came up with the straw yellow suggestion and that's what made it work - thanks Courtney!
I wanted to include a quick tut on mixing. I use my 1/8 mandrels and punty cut lengths of glass to them using whichever ratio I want. I then heat the glass on each mandrel into a gather and smoosh them together then slowly stretch and fold the glass until it's well incorporated. Actually it's not so much of a fold as I try to slide the glass over itself to avoid making too many bubbles. When I feel that it's mixed properly I pull the gather into a rod/stringer. That's it.
Hey, I just saw that this tutorial got 5 stars - Yipee - thanks!!!
