Toscana Milk Paint is used to create a beautiful historic-looking patina. Simply mix this high-pigment powder with water and you get gorgeous, rich casein milk paint. It’s all-natural and has been used for thousands of years. Use over top of One-Step Paint for a unique “layered” look, or use in conjunction with Legno Gesso on top of raw wood. $21 For more information, watch Amy’s YouTube tutorial on how to use Toscana Milk Paint.
