I was looking in my paint cupboard for spray paint and found this darts case it about 40 years old, I made it from mahogany when I was younger it's a good idea if you play a lot of darts.
Drill three holes in a square piece of plank wide enough to place darts in, then saw cut two X'S into the top for flights and run a length of sand paper through the x cuts to shape and then shape the case simples.
