I was looking for these artists from the Twin Vision studio to put their work into my Virtual Wish List (they made fantastic glass installations as well as interesting face beads)... but I've come across this tutorial for beadmaking and moldmaking on their web-site.
This is not a usual tutorial to find in Internet! Once I participated in a process of making something like this. It would not be hard for me to do this again, if I needed... except for the equipment, of course. I would need to find an actual glass artist's studio for glass melting. Honestly, I do not see that happening any time soon :)
I've met the sisters artists at one local bead-show. Maybe next show (or next after the next one:) I will buy one of their glass face beads. They are very unique and very beautifully done!
