Since I've been trying to improve my knitting skills, I picked up a stack of circular needles from the thrift store.
They're in great shape - except none of them had any sort of size markings on them. Are all circular needles like this? The previous owner had attached stickies to a couple of them marking the size but the rest were a mystery.
First I had to figure out what size the needles were. I did it by comparing them with my marked straight needles, although they do make a needle gauge for this. Then I wanted to mark them so I would easily know what size each needle was. Here's what I came up with:
Number beads, attached to a safety pin, then clipped to the circular part of the needle.
Place the appropriate numbered bead onto the head pin, clip to size, loop, and attach to the circular opening at the bottom of the safety pin.
Here's a good picture tutorial on how to use a head pin.
That's really all there is to it. And now my needles are nice and labeled.
