An 1882 pattern that looked like a conifer in an engraving wasn’t so tree-like in real life. 2 days of knitting and 12 variations later, I think I have something that suggests a Douglas Fir.
My pattern has a 16-stitch, 2-row repeat. The wrong-side row is purl across. One 16-stitch repeat will be about 3” wide at gauge. It takes about 1 hour to knit 3.5” of a 50-stitch-wide (3-repeat) swatch.

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

100 yards of Cascade 220 Light Fingering makes about 10 inches of a 50-stitch-wide strip at gauge.
