Taking a cue from NASA naming conventions, I will call this YarnEx.
I swatched it, starting with size 7 needles and switching to 6. I usually need to go down one size when knitting back and forth instead of in the round.
I shouldn't cast on for another sweater until I finish the Basalt Tank. But I really am itching to see how the colors will interact when I use it in the round. The swatch shown above has 1/4 of the stitches needed for the Model des Monats I chose.
