Question ...do others just use distilled water on WP
Nap
I have tried distilled water, and water from our de-humidifier reservoir (which I guess is the same). On a wet palette I don't think it matters. Our local water is very "hard" but I've not seen any ill effects using it in the wet palette. That said, I have painted swatches of the primary colours using both distilled and tap water and diluting the acrylic with the water. I haven't noticed any discernible difference in hue or consistency.
