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. It teaches me to check the yardage amounts on the pattern, and buy enough to complete the project. So, newbies, learn from this and you won't say very many bad words......Terry.
