I said there was something interesting going on with Cotswold. I said that it bubbled - big bubbles rising through it, not the fireworks sparkle like turquoise, and not the big bubbles of not sufficiently dried bead release. Just bubbles forming and rising to the surface and popping.
And check this out - this greenish (by comparison) smear of Cotswold on the turquoise melange of background - did some interesting things.
The base under the Cotswold was a blend of probably Marvo Turquoise and Dark Turquoise.
