First step is to make something integrating a yarn dyed with thermachromic pigment. I decided an ear warmer would be a good platform as the heat wire element might enhance the ear warming function as it heats up to change the yarn color.
I like the way the yarn blends in. Makes for a more dramatic reveal! Now to test it.
Thanks to Laura and Unstable Design Lab for providing the dyed yarn and Wayne for the assist with testing the needed wattage. I’m still unsure of how to actually functionally power this project, but I think it is an interesting idea.
