If you like to spread paint, slice paint, twist paint, apply paint in globs, and generally push paint around you probably use palette knives/spatulas. They can be expensive, though. Thanks to a tip from AMAZING artist and wonderful person, Cindy Schnackel (https://cindyschnackel.wordpress.com/), I don’t worry about palette knives anymore. Why? Because of those free plastic cards that arrive in the mail. Companies send them as part of their promotional activities. Expired gift and credit cards are good, too. These plastic cards have fine edges, are firm but bendable, and come in all sizes. Also, if you repurpose them they won’t end up in a landfill or the ocean. Wonderful! Thank you, Cindy!!
