Experiment

Wonder what would happen to tie up canvas as though to tie-dye, but just to set wrinkles? Threw some coins to get a random spread, tied up the canvas, got it wet, and let it dry–thought that might help to set wrinkles (results inconclusive). Later untie the strings and spread out the canvas. Hmmm, looks like a topo map. Priming the canvas flattens the "mountains" a bit. Give it two coats both sides. This takes a couple of days prep. Today rub on the pigment–burnt sienna–very interesting, but not quite the right color. Will re-prime tomorrow & use raw umber so the canvas will look like leather. Check back tomorrow and see.
Oh, a 100yd. roll of canvas arrived. Impossible to move as is (130lbs.) so RS builds a gizmo to roll canvas smoothly onto another roll. Look.
