One of the glass rods which I worked with in the "40 shades of blue" project at Spruill Arts Center last summer was a rod which looked like it was a mixture of opaque sky blue and transparent blue-grey. It was labeled "Capri", but it wasn't the shade of aqua blue normally associated with that color. That gave me the idea of mixing transparent and opaque glass. I take two rods, tape them together and use them as one rod to layer glass on my mandrel. This is the result:
I like the effect and I'll be using the beads in my jewelry. Watch my Etsy site (www.etsy.com/shop/DeborahDRoss).
