I recently had a hankering to knit a pair of socks using DPNs, despite my love of circular needles.
So I ordered a set of double pointed needles from Knit Picks, which arrived the other day. These are just as pointed and slippery as the Options interchangeable needles in nickel, and a pleasure to use.
The set comes with five of each size (2, 2.25, 2.5, 2.75, 3 and 3.25 mm). Having never previously knitted anything thinner than DK yarn, using a 4 ply sock yarn on 2.5 mm needles came as bit of a shock. Anyway, I have just turned my first heel and picked up the stitches to begin the foot.
Can thoroughly recommend the Knit Picks DPNs to anyone who likes their knitting fast and dangerous.
