Learners will need:
Watercolor paint (any kind or brand will work -- ideally, the kit will have the three primary colors as well as white and black)
1 or 2 brushes (the one that comes inside the kit is fine; ideally learners will have a thicker brush and a thinner brush) 
Watercolor paper (we will need 2-3 sheets of any size for class. Larger paper is recommended, but any size will work. Note: regular drawing paper doesn't absorb water and paint as well as watercolor paper does and can be more messy due to extended drying time)
A cup or small dish to hold water to rinse brushes
A flat surface for painting (should be somewhere that would be OK if paint or water accidentally spilled; you may want to put down paper bags just in case. Watercolor tends to be an easy cleanup, but sometimes paint can get messy.)
Paper towels (just in case of spills)
