To keep with my vegan lifestyle, I double-checked that the supplies I use in my projects were in fact vegan. I found that I will need to edit some of the products already residing in my studio. Going forward the list below will guide the buying decisions for my studio supplies. I ran accross this website that did the product investigation already, so all I needed to do was to confirm what in my existing stock was vegan and make a purchasing plan for future supplies. I like keeping things simple, so I looked for brands that were consistently vegan in their philosophy and products. That turned out to be more difficult than I originally thought as many brands had exclusions to this or that. By the way, most Ivory Black and Paynes Grey are made from charred cow bones.
Here is my supply list of preferred brands that are vegan.
