This eye-catching pattern is from Weldon’s Practical Needlework, vol. 8, p.5, ca. 1892. A lot of pattern is packed into just 4 rows but the results are worth it! Seaweed stitch could be used for anything you choose: scarves, shawls, baby gowns, etc.
This pattern has a 14-stitch, 4-row repeat. The swatch has 3 repeats (14 stitches x 3) and 1 selvage stitch on each side. It took me 1 hour to knit 2 inches of a 44-stitch-wide swatch. Thread color used was “Frosty Green”.

Skills needed: cast on, knit, purl, yarn over, double yarn over, k2tog, p2tog, SK2P and bind off in knit stitch.

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

65 yards of Aunt Lydia’s Classic #10 crochet thread will make about 10 inches of a 44-stitch-wide strip in the stated gauge.
