Why was that one strand so thin…
Oh. Oh rats. It was Arroyo, ie about 300 yards per skein vs the 200 yards per 100g skein of the Rios, and it looked it, and I stopped, found a similarly-dyed skein online in the right weight–judging by the picture, wish me luck–ordered it from across the Bay, nice and close by, put the afghan away and hoped.
I really wanted to work on it.
And went out and checked on the mango tree because I needed that.
So the plan is: I’m going to get the new yarn, weave a strand around over and through kitchener style over all the existing stitches in that grouping–ten, I think–and then work the original strand back out of there with the replacement already in place.
Or maybe it would be simpler just to undo the entire three rows but I don’t want to.
