Well. I found some glue and put the broken needle back together. It seems to be holding, so far. Additionally, a set of size one and size two needles from Comfort Zone arrived. My theory is that a set of needles that look like toys won't offend airport security personnel. Also, icord is a pain on a long circular needle.
The fearless fiber socks I started Friday got knit almost as far as the ankle, but only one sock. This morning I decided the fit was unacceptable and ripped them out and started over. The new sock features a braided cuff as described by Nancy Bush, and I stepped up a needle size more for the leg, which had been too tight. No picture yet, but the sock is gorgeous to my creator's eyes.
