so i too just started to knit socks this summer, after working on an ethnic multi-colored legging project for a while.
I'm not a newbie, but I thought dye lots were a thing of the past. When I realized I hadn't purchased enough yarn for the socks I'm knitting, I went to a store and bought some yarn. Waaaaaaayyyy too light. Wrong dye lot. Having driven almost fifty miles in total, I finally found a ball of the proper dye lot.
