I use absolutely non-toxic and absolutely awesome Mythic Paints. They compare in price and exceed in quality the regular household paints. For more information visit Mythic Paints site. If you would like to learn more about the effects of toxicity in the regular household paints on our environment and our health a good write up is on this site.
For all the pretty details that give the mural it’s “bang” I use artist grade acrylic paints: Utrecht & Golden.
I can also add upon request super fancy elements with glow in the dark paints or sparkly crystals.
