Northwest Nature Shop offers both a Summer and Winter Night Sky stencil in two sizes, 8 feet and 12 feet. These astronomically accurate stencil kits are made for ceilings and come complete with brush and a “special formulated luminous paint which absorbs ambient light, and is practically invisible on white or off-white surfaces”. Their website claims the stenciled stars can be applied in 1-2 hours by a child as young as 12 years of age. What a fun activity to do with your children!
