The socks were fun to knit. I used a ball of Opal Neon sock yarn (no longer manufactured) and 2.25 mm needles. I have switched from Bamboo to Boyce metal needles. They are as light as Bamboo needles, but much sturdier and less expensive since many of my needles disappear into what my daughter calls "the mom zone." I really like these needles, but have not tried them as yet with really slippery yarn.
Knit on Merrily!
