Forgive me this strange comparison, but when I first took the orange cormo/silk yarn off of the niddy noddy, all I could think was that it looked pretty rough. Perhaps you are a fan of the caterpillar, but I much prefer the butterfly. In this case, a freshly washed and dried hank of yarn. . .
It just puffed up and filled out so nicely. Amazing what a difference a little soak in some bubble bath can do for some yarn.
This yarn had the added problem of being composed of one bobbin that had been laying around for who knows how long and one freshly spun bobbin. There was no real way to tell if I had the correct amount of ply until after the bath. Either I did a good job or cormo is really forgiving because it hangs as straight as can be. Whew!
