Double-Pointed Needles (DPN)
Double-pointed needles (DPNs) are short needles with a point at each end, used in sets of four or five to knit narrow tubes like socks, mittens, and hats.
Explanation
Double-pointed needles, often abbreviated DPNs, are short knitting needles with a point at both ends. They are used in sets, usually four or five needles, where the stitches are divided across three or four needles while you knit with the last one. This makes it possible to knit narrow tubes in the round, such as socks, mitten fingers, and the top of hats, where even a short circular needle would be too large. Many find DPNs tricky at first because stitches can slip off easily, but Magic Loop and short circulars are popular alternatives for those who prefer them.
