Really fascinating- what makes it pochior? Pochoir?

Very Nice! Thank you for sharing.

How thick is the mastic? It looks really thin.

Lovely, I really love the one that's purple, blue and golden looking, it reminds me of a poam called The Way It Is by William Stafford

Its so funny i searched for using a dremel with dry point and you popped up, love this, it reminds me of the flow of water
