I just received some glow-in-the-dark cord from "Cool Glow Stuff!". I bought the 1/16" and 3/32" diameter cords, since those sizes should braid well with paracord. The other glow cord I've used is from TAD Gear, shown on the right. The two lanyards I made on the left are made with the Cool Glow Stuff! cord and the one on the right is maroon paracord and TAD Gear glow cord.
