Coastal yearnings

OK, the picture preceding this is the sketch I did at last Thursday's life drawing session.

This is the same sketch, I "fixed" the charcoal by applying linseed oil to the back of the paper, the oil soaking through binds the charcoal to the paper tightly enough it's pretty much archival.

Then, after the oil dries the paper is translucent, allowing me to paint with acrylics on the back side of the paper, the colors showing through the translucent paper.
