Finally got all my dye chips made. Someone tell me not to try to do this in a hurry with 20/2 silk next time, 150 wraps per chip! A good motivation to move to 10/2 tencel, so I may.
Here's the substrate chip. This was a good exercise, as it illustrated to me the variation in color of the silk yarn, as well as some anomalies, such as the dark line in the middle. I was thinking this (dark streaks) was showing in my dye chips due to some error on my part. But it is part of the undyed yarn.
