What is your preferred type of canvas?
I use canvas rolls from Big Duck Canvas in Texas. I order their double-primed 60”, 72” and 84” cotton canvas rolls in 25 or 50 yard rolls. They’re made of a very durable, heavyweight material so carrying the roll can be prohibitively heavy and awkward at first. The tradeoff is knowing the quality and longevity compared to might ultra-light pre-stretched canvases.

How do you clean paint water?
I use Golden Crash Paint solids waste water cleaning system to remove acrylic from water
