Because of the strength of carbon fiber, these needles were originally intended for sock and lace knitting, going all the way down to a tiny 1mm size! But now they come in a variety of larger sizes, and can be used for all sorts of different projects. We love these needles for both sock knitting and sweater knitting alike.
We definitely think a beginner can handle these needles, as the carbon fiber won't be too slippery for your stitches, but we also think advanced knitters will love the speed of these needles.
Double pointed needles are great for knitting small circumferences in-the-round if you don't like using circular needles. Things like socks, mitts, and sleeves are perfect for DPNs.
