Point Protectors
Point protectors are small caps placed on the tips of knitting needles to keep stitches from sliding off during transport or breaks in your work.
Explanation
Point protectors are small, soft caps made of rubber or silicone that fit over the tip of a knitting needle. They are used to prevent stitches from accidentally sliding off the needle when the work is set down or taken on the go, while also protecting the needle tip from damage. Point protectors are especially useful for projects using straight needles or several double-pointed needles at once, where stitches can easily fall off both ends if the needles aren't secured between knitting sessions.
