Holiday Light Shows
As I did with my spider build I used foam board to make the tombstone shape just by rounding the top edge off of my foamboard. Using a 12mm apscing template I marked the postions of the hole for the WS2811 leds to go into and then made the holes the right size for them.
I did the same for the letters R I P and filled those with LEDS.
I used 146 LEDs on this model(including the two blanks in between the edge and the letters)
