The surface of oils.

[Chris Saper]

Beth et al,

I think that the problem may be in combining "build-up" and "reworking the form" . Do you remember that Bill W would patiently and delicately scrape off any ridges before proceeding with the next session? Daniel Greene uses much the same approach with the fan brush, which not only gets rid of the ridges but controls future glare.

Of course none of this matters if you are painting alla prima. The older I get, the more I find that needs to be corrected, and I am always trying to use more paint, but for me it needs to be on the very last layer.
