I googled and found that there is such a thing… and saw in a KH blog thread that Ingrid had bought some (but not yet used)… has anyone used any yet?
I’ve only found two references to glow in the dark yarn so far:
Glowyarn and the US site is supposed to be glowyarn.com but I couldn’t get that to load
"…developed by mixing, melting and extruding Polyester chips with Photo-luminescent pigments" sounds kinda yucky/toxic but hey! it glows…
Nightlights comes in off-white but glows flourescent green, DK weight
Sounds like fun
