Done!
I love the colour of this yarn but confess that I do not like the Regia as much as Opal sock yarns to knit with. Unfortunately, I bought ten balls on sale. Ah well.
As for the Magic Loop? The jury is still out. There are several advantages for me, but I still dislike working with circulars and their disappointing habit of kinking and snarling. Speed may be the deciding factor. It certainly is faster than juggling four or five DPNs.
