I got this mixture from a random video like 2 years ago lol. But basically the baking soda adds body and texture to the mixture, and I think it also helps it stay softer to carve. I’d guess around half/a third of the mixture is baking soda. The rubbery/plasticy textured paint helps make it less crumbly. I only add a little bit tho The “ chalky textured paint and guesso “ I add way more of, it adds color and gives it that nice clay texture :)! And then when I first let it dry it crumbled too much so I added mod podge to act as a binder ig idk man I was just throwing stuff in a bowl #art #artistsoftiktok #paint #painting #lino #linocut #linoprint #carve #carving #sculpture #arthacks #arttips #arttipsandtricks #arttutorial
