You won’t notice the difference while working with this yarn but when using it out in the cold weather you will feel the difference. Designed to retain heat while being worn outside, the yarn does go back to room temperature when it is no longer exposed to the UV rays.

YOU WILL NOT BURN YOURSELF WITH THIS YARN. The yarn does not get hot enough for you to burn yourself. Check out this video of the yarn in action during a demo at Creativation this year.

      Heat Wave will be going online at Yarnspirations starting September 23rd. I am not sure if it will be going into other stores other than JOANNS but you will be able to purchase online.

    This yarn will be ideal for chemo hats and for those who are unable to regulate their body temp post chemo, like my son.
