I broke down and bought some of the cotton/lycra sock yarn from
Greenwood Fiberworks that
Grumperina was raving about the other day. Apparently I ordered it right before her most recent post because she promptly sold out of the cotton/lycra blend shortly after I ordered.
Take a look:

I love it. It's stretchy, thin, fabulous, and should make GREAT SOCKS. BUT, the pink looked a little more vibrant/raspberry/magenta in the photo on etsy; in person, it's a dusty rose. Me no likey as much as a louder, brighter, clearer color. Perhaps this is my chance to dye?
(Note: I will be ordering from Greenwood Fiberworks again- the shipping was lightning fast, well packaged, and totally professional- I am WAY impressed with her and I think this was more error in judgment on my part than anything else).
Some preliminary research indicates that kool aid dyes do not work on cotton. Damn. Any suggestions? And, color experts, is it even possible to overdye this in such a way that the color is deeper and more vibrant (ie not dusty)? All thoughts are much appreciated...
