While I'm familiar like you are with Mark's recipe for the canvas stain, I'm in a pickle.
I have W&N burnt umber, which I think is fine. But I cannot decide on the white to use as I don't have the quick drying one. I have these:
W&N titanium white
Old Holland titanium white
Michael Harding titanium white
W&N flake white hue
I also have Gamblin white oil ground, but they told me it can only be used up to 1oz Gamsol:32oz Ground, so that cannot work as I need the stain to be almost fluid).
Thank you so much!
