Last June when I took the class from Melanie Moertel, one of the things she showed us was how to make our own multi layered murrine. Prior to the class I had been making very simple one layer murrine, and had not ventured further. I took out my notes the other day, and started to make some. You can see the murrine in these beads (the little round flower like decorations on the beads).
You can find these beads in my Etsy shop.
Hope you have a great day!
