I did the same on some wool blend cream hose I got from SWK. I used a different dye royal blue dye from Hancock Fabrics, as they did not have Rit. One run through the dye and they turned a heatherish light blueish/purple color, which really works well with my kickball shirt actually. I have a navy pair of hose from Rocky though.

How many times did you do the dye job?
