First attempt: I used the citric acid crystals instead of acetic acid, the ph was probably 4.4, and 150ml dye bath in one jar and 200 ml dye bath in the other 2 jars. My ties were too tight so they yarn was not even. The color was the same on all three chips. The color did not fully exhaust.
Second attempt: Even color chips. I made new dye bath using vinegar instead of cirtric acid. The ph was 4.5-4.6. I used less ties and looser ties. I also used 250 ml of dye bath. However,
I still had color present in the dye bath after it cooled-but clear color. I am thinking it is how I mixed the dyes initially.
