These are so easy and adaptable that even I can make them, and I'm not creative. I went to Lowe's and experimented with the different sized clay pots until I'd found four pots and two saucers that worked well together.
I spray painted the largest saucer with Stone spray paint. It could also have been painted black or red and turned upside down to sit the largest pot on top. I spray painted all the pots white.
I used aluminum foil and painter's tape to cover everything but the rims of the pots.
Painter's tape is so wonderfully forgiving. It can be positioned easily, and if a mistake is made, it can be repositioned with no trouble.
And it's easy to fill in the gaps.
I used Rustoleum paints, but any good outdoor paint will work.
First, I sprayed the undersides of the rims,
then I turned the pots over and finished. [I also sprayed some extras for something else. ]
After 24 hours, I removed the tape and foil, used a stencil to draw the doors and windows [I said I'm challenged. I can't even draw a straight line.], and painted them with black gloss acrylic Patio Paint. An inexpensive lantern with a flickering LED candle inside finished it off. I plan to place the pebbles from that bag all around the base to give it the look of a lighthouse on a rocky cliff.
