This is a picture of some superwash Merino yarn that was dyed with the Dharma dyes. The socks made from this yarn have been washed twice.
WTH? All of the turquoise has mostly washed out. The green was made with turquoise mixed with Golden Ochre (a Jaquard Dye), the purple was Dharma Fuschia and Turquoise. The remaining stripes of dusky turquoise was a mixture of Jaquard Turqoise and black (and maybe something else, I forget). I hate to think what they'll look like after wash #3.
I have emailed Dharma, asking them to email me so that I can send them this picture. When I emailed earlier, asking if I could return the blue dyes because of rinsing problems, they contacted me, and because I had used some, I was unable to return them. Now, I'm really P.O'd, and I want them to take them back. I've also posted this picture on their Facebook page.
The real issue is that I have sold all the yarn in this colorway, along with most of the fiber in the same color mix. The other colorways that I've dyed have also mostly sold, and they also contain the turquoise dye and mixtures.
I know from my own experience (I am not proud of this...), that if something is wrong, most times people will not contact the supplier, but will bad-mouth the supplier to all their friends. This is my biggest fear - that people will think that Fiber Voodoo doesn't know how to dye stuff, and the dye doesn't stick.
I have been dyeing for over 20 years. Because of the issues I had in October, I checked the pH of my vinegar water - it was pH 4. I steamed the yarn for over 30 minutes (I got distracted and when the timer went off, I was in the middle of something else). There is no reason for this dye not to have struck the fiber, particularly since it's superwash, which is a dye magnet.
I will let you know what happens. I'm now reluctant to keep any of the Dharma Dyes, and think I would like them to take them back and give me a refund. I'm going to continue to use my not-so-old Jaquard dyes, which are now stored in the house...
So, in the future, I'll stick with the more expensive but tried and true dyes that I'm used to. This has been a very expensive lesson.
