"Glow Stick" is a rainbow of bright neon colors, with streaky/speckly texture. I haven't tested it myself, but most of the dyes in it are black-light-sensitive, too! These skeins' colors pool, meaning they repeat (albeit somewhat chaotically); a savvy crafter can manipulate this in fun ways in their work!
This yarn base, Home, is soft-but-sturdy worsted weight yarn. I'd use it for sweaters, hats, scarves, blankets—it's versatile, but still great for next-to-skin wear. It's 100% fine organic merino in a 4-ply; 219 yds, 100g. Hand wash, dry flat.
