I like painting with plasticine. That is material for kids' creations something like clay. But I paint with it. I began to paint with plasticine many years ago. I was a student and I didn't want to spend money for expensive oil paints and I decided to try with plasticine.
and it worked! and still works. I like it. And paintings by plasticine look really interesting.
Plasticine is a putty-like modelling material made from calcium salts, petroleum jelly and aliphatic acids. Plasticine is used extensively for children's play, but also as a modelling medium for more formal or permanent structures.
