That's a really nice tut, I haven't seen it before.
Thanks for posting it, I bookmarked it for later.
Unfortunately it isn't it.
The one I saw is an older tut.
I found marble beads on Heather Trimlett's website and they look very much like what I remember was in the tut.

Does anyone know if she shared her technique for these anywhere?
There's no mention of publications on her site that I saw to point me where to look.
This is driving me bonkers. Lol
