This may just be cooler than my boyfriend's Hypercolor color-changing t-shirt from the early 90s! New from HiKoo, Abracadabra is a color changing yarn that's activated by UV rays. Inside, it's a calm shade of natural. But, take it out into the sunlight and it turns into a vibrant color!
Use this dk weight yarn to knit shawls, wraps, sweaters, hats and more.
Abracadabra is available in two shades, Natural -> Pink and Natural -> Purple. Either color you choose will wow your friends and start conversations wherever you go.
