I just spent 20 minutes rummaging through my knitting supplies because I could have sworn I had a set of 4 mm rounds. I made a massive yarn knot much worse, and did not discover the needles in question. I did, however, discover I have 2 sets of 4.5 mm and I think a total of 7 4-mm DPNs. How? I don't know.

Since I am working a baby sweater and only need the rounds for the shoulders, I am just switching to my longest set of 4 mm and diving in for an extremely awkward 15 rows, rather than derail this knitting party I got goin' on over here. I'm going to be in the corner, sippin' wine and knitting granny style...
