I think this is pretty good for a poet who needed to be dragged to an art class a few years ago.
I picked up the idea for this technique at http://www.brigidmarlin.com/Pages/Mische.html
but fudged considerably; playing with eggs sounded too messy and I didn't get around to sanding, probably haven't been getting the layers thin enough or even enough. Doing it wrong like this makes for nice effects--though looking around her site makes for an embarrassing comparison. Maybe sometime next life...
I used casein & oils on 5X7 canvas, with a no-hair brush (alligator clip on a disposable chopstick, holding a thin sliver from a stiff rubber pipe.)
