I went through a knitting phase back in the mid-2000s but never got good enough to make anything more than a scarf. Realizing it would take me months to make a sweater really turned me off, so I switched to cross-stitch instead.
Turn my defeatist attitude into your gain! These are US size 15 knitting needles or, for the rest of the planet, 10 mm. They are made of plastic (I think, but it doesn't feel acrylic to me) and are 10 inches long.
