Potholder stitch and periodicity

Ordinarily, crocheting in variegated yarn produces alternating patterns because the crocheting goes back and forth. But when you do potholder stitch (see my earlier post) the situation is different. Each row only shows on one side, so all the rows on the same side go in the same direction. That means that a pattern will tend to be regular.

My aunt got some yarn for me to make potholders, and it’s white yarn variegated with five rainbow colors (not blue or indigo). Each white or colored section takes about 6 inches, or 3 stitches. So my 30 stitches turned out to be nearly perfect to make the yarn go through exactly one cycle per side. I thought this would mean that the potholder would have boring nearly-vertical stripes, but it turns out that the dyeing of the yarn is not quite regular enough to permit that. It’s close, but it has zany variation! Take a look.

I didn’t bother to flip my pictures this time: my computer takes all its pictures as mirror-images, which is sort of annoying, but this way it looks as if I crocheted right-handed. Shrug. 🙂
