Prime the MDF board of the wooden wall clock with white craft paint. This is best done with a painting sponge.
Once the paint is dry, spray the back of the stencil with "fix it adhesive spray" and place it on the round plate. Provide the craft paints you want to color the plate with. Stenciling is best done by picking up some paint with a dry sponge dab brush and carefully dabbing it onto the selected painting area.
Color the entire clock in this way, little by little. Once all the colored areas are designed, pull off the stencil and clean it with water. Let the paint dry.
Label the clock with numbers using a marker. Mount the clock movement to the plate and put the clock hands on it.
