On a side note:
This was the first "nice treat wool" I bought for myself as a beginning spinner. Knitting with it brought back memories of all the self criticism I gave myself for bumpy inconsistent yarn.
Over the course of knitting these 4 sock monkey sweaters, I knit from the more experienced yarn to the beginner yarn. It was fun to see how my consistency improved even over just 4 ounces. I remember being surprised that the sweater acutally looked decent and like "real yarn".
It was fun to revisit this yarn after it laying around for so long in the stash.
