A couple of months ago, I had an unhappy surprise at Afghan Sunday. I laid my completed blocks out on the floor and stood back to look them over - and saw that the Carol Adams square, which had been in the shop window for a while, had faded! Martha (the shop owner) was quite apologetic and offered to replace the yarn; but even using her secret underground shopowner connections, she was unable to locate another ball of off-white Cascade 220 Superwash from the same dye lot.
Finally it occurred to me to post to the Ravelry group dedicated to the GAAA. After all, it has 450 members, and many of them are using the same yarn I am. And sure enough, within a few days, someone messaged me to report a sighting of the appropriate dye lot at her LYS! I phoned them right away and had them send me, not just one, but three balls. I should have enough yarn now to knit all 24 squares and the heavy cabled border if I want. Thanks very much, Heather (creativechick)! Also, thank you to the friendly, helpful staff of Knit-a-Bit in Westfield, NJ.
Now what am I going to do with that non-matching Carol Adams square?
