Supplies needed for the class:

#1. Paint:  Acrylic paint in a variety of colors. You can purchase acrylic craft paint from your local craft store, such as Plaid or Americana. For a more expensive option, there is Liquitex or Windsor Newton. You should have the following colors: dark and light green, white, yellow, brown, red, dark and light blue, pink, purple, black. Other colors are optional. 
#2. Paintbrushes: You will need a few different brushes. A large flat brush for large areas, such as backgrounds. A few smaller flat brushes (we use those for the majority of the painting). A medium and a small round tip brush for the final details. For most of my paintings I find that these brushes are enough: # 12 Flat, # 8 Flat, # 12 Round, # 8 Round, # 2 Round.
#3. Canvas: Canvas board or stretch canvas work well. Sizes between 9 by 12 inches, and 11 by 14 inches will work well, other sizes are perfectly fine also. Alternative painting surfaces can be wood, cardboard, and heavy duty paper, such as watercolor paper or cardstock.
#4. Palette: No need to buy a fancy pallet. A paper plate, or a recycled plastic container will work well. 
#5. Cup with water to wash brushes in, an old towel, or paper towels to wipe the brush with. 

Don't forget to wear appropriate clothing for painting!
