One day, while I was planning my trip to a yarn festival, my husband asked me to get him some undyed yarn while there. “Hope he doesn’t destroy it”, I thought. You know… all that money could be spent at some booth with pretty skeins. I did get him the yarn in the end. And he started studying a lot about acid dyes and temperature, and pH levels (he’s a nerd!)… and then he showed me his creations.
