Under The Sea Socks

Under The Sea Socks by Ophelia's Stitches

What is Being Made

Under The Sea Socks is a downloadable knitting pattern for women's socks designed by Alex UpChurch. This intermediate-level project creates fitted socks available in three sizes: Small (7" leg, Women's US 6–8.5 shoe), Medium (8" leg, Women's US 9–11.5 shoe), and Large (9" leg, Women's US 11–13.5 shoe). The socks feature a decorative lace pattern inspired by an underwater theme, combining functional construction with visual interest suitable for everyday wear.

Knitting Techniques Used

This pattern employs several essential sock-knitting techniques appropriate for intermediate crafters. The socks are constructed using the magic loop method or double-pointed needles, worked in the round from cuff to toe. The pattern begins with a German-Twist cast-on or any other stretchy cast-on method to ensure comfortable cuff elasticity. The design incorporates lace patterning worked across the leg, creating an openwork effect that defines the "Under The Sea" aesthetic. The pattern uses a repeating 13-stitch multiple, allowing for customization across different sizes. Construction includes a set-up round for certain sizes, followed by repeating lace rounds that progress down the leg before transitioning to the foot and toe sections.

Stitches Used

• Knit (K) – the fundamental stitch forming the base fabric
• Purl (P) – creates textured contrast, particularly in the 4-stitch purl sections within the lace pattern
• Yarn Over (YO) – creates the openwork holes characteristic of lace patterns
• Slip, Slip, Knit (SSK) – a left-leaning decrease used to balance yarn overs and shape the lace motif
• Knit Two Together (K2tog) – a right-leaning decrease creating directional shaping within the pattern
• Make One (M1) – an increase used in the set-up round for specific sizes
• Ribbing (K1, P1) – creates the stretchy cuff that holds the socks securely on the leg

Materials and Specifications

The pattern calls for Premier Yarns Serendipity in the Surf colorway, a 4-ply yarn blend containing 50% Superwash Wool, 25% Rayon, and 25% Nylon. This fiber composition provides durability, softness, and easy care through machine washing. The yarn yields 230 yards per 50-gram skein, and the pattern requires 2 skeins of the main color (MC). Scrap yarn in a contrasting color (CC) is used for the cuff and provisional cast-on techniques.

Needles required include a US Size 2 (2.75 mm) set of 4 double-pointed needles (DPNs), which work in conjunction with the yarn weight to achieve the specified gauge. The pattern gauge is 8 stitches by 10 rounds equals 1 inch (or 10 centimeters) when measured over stockinette stitch, ensuring proper fit across all three sizes. Additional tools include a darning needle for weaving in ends and finishing, and an optional stitch holder for managing stitches during construction.

Pattern Structure and Construction

The sock construction begins with a cast-on of 52, 64, or 78 stitches depending on size, using the German-Twist method or another stretchy technique to ensure comfortable elasticity at the cuff edge. The cuff is worked in 1x1 ribbing (alternating knit and purl stitches) for 12 rounds or to desired length using contrasting color yarn. Following the cuff, the leg section features the main lace pattern, which repeats across rounds with a 13-stitch multiple. The lace design incorporates paired decreases (SSK and K2tog) balanced with yarn overs, creating the characteristic openwork effect. Purl stitches are strategically placed within the pattern to add textural definition. A set-up round is included for baby, toddler, and medium sizes to adjust stitch counts before beginning the main pattern repeats. The pattern progresses through multiple rounds of lace shaping, with each round building upon the previous to create a cohesive design down the leg toward the foot and toe.
