Well, I dyed some Knit Picks lace weight 100% merino. I used Kool-aid Pink Lemonade and Lemon-lime to dye parts of the yarn and then overdyed it all with royal blue wiltons icing dye. It did exactly what I wanted it to, turning it to varying shades of teal, blue, and purple. Have a look . . .

Here is also a picture of what it is looking like knitted up:
I ended up knitting them on 0us/2mm needles. I swatched a few pattern designs but didn't like what they did to the colorway and decided that just a plain stockinette stitch would be the nicest.
