I continued work on the board shown yesterday and managed to take it along without picking up a greasy surface. I feel so great about this! This scanned image doesn't really show the surface very well but it's not at all greasy and has good depth. I'd say that in the future I can do better with gradation, etc, but for now to achieve technique is just fine by me.
Next I'll transfer the lily and begin building up an opaque base.
Here's a peek at my kitchen table workspace. I've just switched over to the lamp holder clamped to the arm of the chair. Works great--nice and bright and no glare at that angle. Once I retire and have more time I will again set up a dedicated studio space.
