This is the 3ply Paternayan tapestry yarn, with a 3, 5, and another 5 minute dip in the weak vat, from left to right.
Below is the Harrisville Highland 2ply wool with the same 3, 5, and 5 minute dips. The results are so much paler than the tapestry yarn. So I concluded that not all wools dye the same. Perhaps there is more spinning oil in this yarn than the other, despite my scouring it before dyeing it. It still is extremely beautiful.
Using the wool yarn that I recently dyed in goldenrod, I used the weak vat to over dye the rich golden yellow in one dip of 3 minutes and a second dip of 5 minutes. I am very pleased with the results.
I then took those same three samples and modified the colors using a warm bath with ferrous sulfate (iron) in it. The iron causes the color to become a little duller than the original. I just love this ability to dye one color of natural dye and then modify it using indigo and iron!
My last set of samples on the tapestry yarn, from left to right are:
Goldenrod, goldenrod and a 3 minutes dip in the weak indigo, goldenrod with a 3 and 5 minute dip in indigo, goldenrod and iron and goldenrod with a 3 minute indigo dip followed by iron.
