  3. Decide what underglaze color you want your background to be.

Underglaze Painting

  3. After letting your pieces dry thoroughly, apply your second layer of underglaze with a brush.
  4. After letting your pieces dry thoroughly, apply your third layer of underglaze with a brush.
  5. After letting your pieces dry thoroughly, apply your blend layer using 2 underglaze colors with a couple brushes.
  6. Let your pieces dry at least 24 hours before class.

Finalize your designs

  1. Create a sheet with your designs on them.
  2. Cut your tracing paper into small sections and using a sharp pencil, place your tracing paper over your design and trace it.

Once you’ve completed these steps, you will be ready for class!
