Thanks Dave. Was trying to take my love of swirls to another place. I created some thick light coloured paint, that I slopped a small blob on, and then drew inside. Expected it to be a gloopy mess. Took a few tests, but worked out eventually.
I really was just messing around trying to recreate something I'd seen in an acrylic pour. Don't think I'll do another too soon. A very impresice process.
