The Undulatus Socks are inspired by Balistapus undulatus, the Orange-Lined Triggerfish, a species of tropical fish from the Indian and Pacific Oceans. It varies in colour, but is most commonly a dark green or blue with orange or yellow stripes. This striped pattern is distinctive and encourages other animals to stay away from this aggressive and territorial fish.
These socks use slipped stitches and simple cables to create the effect of one colour flowing over the other as the two colours are alternated every row in jogless helix-style stripes. Elongating the stitches to be slipped helps keep the socks stretchy and comfortable. The two mirror-image charts are interchangeable, so you can make these socks your own with any sequence you like!
These socks are knit toe-up. They are available in three sizes: Small (56 stitches), Medium (64 stitches), and Large (72 stitches) and are adjustable in length and height. They feature a rounded short-row heel in the contrast colour and a twisted-rib cuff. Corresponding written instructions are provided for the charts.
This pattern requires the knitter to be able to knit a small circumference in the round (either on double-pointed needles or your preferred technique for socks) and clearly explains all techniques for increases, decreases, yarn over short rows, cables, and elongated stitches. Within the pattern you will find links to useful video tutorials as well, so the pattern is accessible to an intermediate (or adventurous beginner!) sock knitter.
Recommended needle sizes: 2.5 mm (US 1.5) and 2.25 mm (US 1)
Yarn Requirements and Sizing
There are three sizes available: Women’s Small (Medium, Large) corresponding to foot circumferences of 18 (20.5, 23) cm / 7 (8, 9) inches and foot lengths of 21 (22, 23) cm / 8.25 (8.67, 9) inches. There are detailed instructions included for adjusting the foot length as well.
The socks require approximately 300 (325, 350) m / 325 (350, 375) yards of fingering weight yarn, divided evenly between the two contrasting colours.
This pattern is designed for a saturated solid or semi-solid Colour A over a background Colour B that can be almost any type of dye — solid, semi-solid, tonal, variegated, speckled, etc. — as long as it contrasts clearly with Colour A throughout its colour range.
