I have been anxiously awaiting delivery of the wool for the Mara Cardigan I will be knitting as part of the Kara_Class (KAL). Everyday I check the mail box to see if I finally received one of those grey (or is it gray) plastic bags from Jamieson & Smith that I have been hearing and reading about.
Yesterday my wish came true. The grey (or is it gray) bag that came was filled with this!
It appears that the "gray" varient appeared later, as an American English varient of "grey". Both have *mostly* the same many meanings. So yes, "grey" is a color, and was always so. Us Americans had to go and be different with "gray."
