These are incredibly easy to make. You just have to bead the safety pins. Its a bit of a hassle because you have to put half the beads on once you've put it on your pants or wherever you'd like. Because of this, I used headpins to attach bead strings to the side that doesn't open, which means the bead strings can still be changed around, but they won't be inconvenient.I did this by twisting the top of the headpin onto the safety pin using small needlenose pliers. I personally put them on the seams of my pants, right near the top of my leg.

Enjoy :)
