I made them almost 2 years ago, using Duet Sock Yarn from A Swell Yarn Shop, and the Waffle Rib pattern from Sensational Knitted Socks. I loved them madly and the pattern was a great match for the yarn. I may knit that pattern again but I will never, NEVER, use that yarn again.
The idea behind Duet yarn is great - a skein of variegated sock yarn sold with a contrasting mini-skein for the cuff, heel, and toe. The yarn was lovely to knit with, and the finished item was soft and comfortable.
But the first time I washed the socks, the yarn bled. As it did the second time, and the third, and the fourth, and the fifth, and...oh dear gods how it bled. Each time, the dark brown overdyed the bright white and green more and more, washing them out to a dull beige. Now, almost two years later, this is what I have:
And just in case you think this is a trick of the light, let me show you the hard evidence:
You can see it now, can't you? Those two little balls of yarn are the leftovers from my once happy, pretty socks, now sad and murky.
Do not speak to me of vinegar rinses, Shout Color Catchers, and other remedies - I have tried them all. I gave up after the first year, there is nothing more to be done. I wear the socks because they are comfortable, and then wash them as I do all the others.
The lesson I have learned from this? (Besides not using that yarn ever again.) In the future should I ever want to do any colorwork at all, no matter how minor, I will swatch the two yarns together and wash the swatch. Possibly a few times.
