I bought 2 yard sticks at Home Depot (roughly 68 cents each) and spray painted them black to match my son's bedroom furniture. I had clothes pins on hand (no idea how I acquired them lol) and spray painted them silver. I redid my son's dresser in black and silver so this matches perfectly.
I used Gorilla Glue to glue the clothes pins in place. I would recommend Super Glue instead since Gorilla Glue expands and I can actually see the glue on this. I'll be sure to use super glue when I make my daughter's.
Be sure to space your clothes pins appropriately. I just eyed it visually with a sheet of 8.5x11 paper.
Drill two small holes into each yard stick and then screw them into place using a leveler. Drilling small holes in advance prevents the wooden yard stick from splitting when screwed into the wall. Dab some matching acrylic paint over the screws and you'll never seem them!
