This no-image, no-name pattern from 1875 has a 6-stitch, 8-row repeat with 4 selvage stitches (2 on each side). Except for the selvedge stitches, all 4 wrong-side rows are purl across.
It takes about 1 hour to knit 4 inches of a 34-stitch-wide swatch.

Skills needed: cast on, slip, knit, purl, yarn over, SSK, k2tog and SK2P.

Gauge is not important in this pattern. Any block-able yarn/thread will work. Make a swatch to check gauge and appearance.

60 yards of Aunt Lydia’s Classic #10 crochet thread will make about 11 inches of a 34-stitch-wide strip in the stated gauge.
