I think I confused many readers with my poor description of too long circular knitting needles in my previous post so this is my attempt to offer an explanation.
Socks, hats, and mittens are basically tubes. And if you don’t want seams in those items, you knit in-the-round and make a tube.
Some knitters use double-point needles to create this tube and others use circular needles. Double-point needles (dpns) are pointed on each end. This allows the knitter to work across one needle, continue to the next needle, and so on in a circle (or spiral). Circular needles are two needle tips connected by a cable. Sometimes the cable is fixed and sometimes it unscrews from the needle tip to change the cable to another length. There are many videos on the interwebs that will give a better description using both types of needles but I just wanted to show why I went from using dpn to two circular needles and then to a tiny circular needle.
When using dpn and working from one needle to the next, a gap may appear at that join aka a ladder. Or the yarn is pulled so tight that it puckers. With circular needles, the piece is knit around and around so there is no definite join at the beginning or end of a needle. You can see the puckered area where I worked from one needle to the next and inadvertently pulled the yarn tighter across the back. This is a common problem when doing colorwork. The yarn that is not worked is carried loosely across the back to keep the tension even on the front. When using dpns, the chance of pulling the yarn tighter at the “corners” is greater than on a straight section.
I had two cable needles, one 16 inches long and the other 24 inches long. Both were clearly too long to knit comfortably. The average foot circumference is less than 16 inches around and the sock would be stretched out of shape. Mine is approximately 8.5 inches around the ball of my foot. Even when working with one, then switching to the next, it was not comfortable.
Part of that was due to the length of the actual needle tip. All of the needles below are US #1.5 (2.5 mm) but the tips (and cables) are different lengths. The top needle tip is 5-inches long, the middle 3 3/8-inches, and the bottom 2-inches.
As you could imagine, working around a 9-inch circle with a 5-inch straight needle would be difficult and uncomfortable. Obviously, it can be done but I knit for pleasure and this was so not pleasurable.
I splurged and bought two 9-inch length circular needles. One US #1 and one US #1.5.
No more puckers. No more fiddling with five double-point needles. It was a bit of a learning curve to hold a 2-inch needle, however, not bad at all. I will have to go back to the dpns once I get to the toe but I’m looking forward to making the second sock and many, many more. I’m a believer.
