For #ThrowbackThursday, here's a 2004 colored pencil floral design that I made using only 4 colored pencils - indigo blue, orange, canary yellow, and light cerulean blue, all Prisma color colored pencils.
If you don't want the mess of painting with acrylic, oil, or watercolor, just pick up a mixed media sketch pad, colored pencils, and a pencil sharpener. That's all you need to make beautiful works of art with little mess or clean-up.
