When DPNs Go Flying, Try A French Knitter
This tool also goes by knitting dolly, and sometimes is given a small face, or spool loom, and its purpose is to make knitted cording, or I-cord. Larger looms of the same kind can be used to make socks, hats, etc. And if you imagine even larger automated ones, you have the idea how they first industrialized knitting in the round.
You can make knitted cords with double-pointed needles, but since that usually ends with one slipping out of my hands and under the sofa, my husband hunting for it, and a lot of anxiety, I now use this for cords, and the magic loop for anything bigger.
My dolly came with a long pin or peg, but I ended up using a crochet hook. You wind the yarn around the pegs once, then carry the yarn around the outside from peg to peg, slipping the last stitch over the yarn, making a new one. This was the first time I used one and after a few false starts, I made this cord. You can see the cord is neatly made and shows off the hand-dyed yarn nice. This yarn I call Winter Squashed.
I got my knitting dolly while visiting Garen Huis in Holland, MI, but your local yarn shop probably carries them too. https://garenhuis.com/products/susan-bates-crystalites-french-knitter?_pos=1&_sid=021b42ef4&_ss=r
