So I got as far on
selenite's green cabled sock as I dare without trying it on him again. Can't do anything further with Maggie's 2nd Cloverleaf Eyelet Rib sock yet, as I need to wait until the 3 mm circs are available from the green cabled sock, then rip it back to the heel and redo the foot with the smaller needles.
So I went ahead and cast on the planned CIC sock, for the Six Sox knitalong pre-start contest, also in the Cloverleaf pattern. I'm using a teal-y blue green yarn, in DK weight, Emu Superwash, the same stuff I used to make
patgund's Blueberry Waffle socks last year. That goes on a larger size set of circular needles. Slightly tight on the size 6's, but doable.
