Buy a nurse a 6-pac of beer in return for some injectors – without needles. Great for dispensing minute amounts of water to keep the paints wet.
I just found 3 pieces of old WC paper, 22×30 with deckled edges, that I squirreled away a decade or so ago. Now I’m working at generating enuff guts to try guache as a WC rather than my semi-oils methods. Been 20 years or more since I applied washes!
