Diagonal Lace Cowl in Plymouth Yarn Sea Isle Cotton – Pattern F951

This free downloadable knitting pattern from Plymouth Yarn Company produces a beautifully textured Diagonal Lace Cowl worked in the brand's Sea Isle Cotton yarn. The finished cowl measures 8 inches wide by 40 inches in circumference, making it a generously sized accessory that sits comfortably around the neck and shoulders. The pattern is rated beginner-friendly, making it an excellent introduction to lace knitting for newer crafters while still delivering an elegant, eye-catching result.

What Is Being Made

The project is a seamless tubular cowl constructed by working a flat rectangular panel and then joining the two short ends together using Kitchener stitch for an invisible, seamless finish. The resulting cowl has a diagonal lace motif that travels across the fabric in a visually dynamic, offset pattern, giving the piece a sophisticated look that belies its beginner difficulty level.

Materials

• Yarn: Plymouth Yarn Sea Isle Cotton – 1 skein (100g hank), shown in color 6 Robin. Sea Isle Cotton is a worsted weight cotton yarn, prized for its smooth stitch definition, breathability, and soft hand — qualities that make it especially well suited to lace patterns where stitch clarity matters.
• Needles: US Size 8 knitting needles
• Additional materials: Waste cotton yarn for the provisional cast on
• Gauge: 18 stitches = 4 inches over stockinette stitch

Techniques Used

• Provisional cast on: The piece begins with a provisional cast on of 47 stitches using waste cotton yarn. This temporary cast on holds the live stitches at the beginning of the work so they can later be placed back on a needle and joined seamlessly to the final row.
• Working flat: The cowl is worked flat in rows, meaning it is knitted back and forth on straight or circular needles rather than in the round. This creates a rectangular panel that is later seamed.
• Seaming with Kitchener stitch: Once the panel reaches the desired length, the provisional cast on is removed and the live stitches from both ends are grafted together using Kitchener stitch — a technique that joins two sets of live stitches in a way that mimics a row of knitting, producing a truly invisible join with no visible seam.
• Lace knitting: The central lace pattern is built around a repeating combination of yarn overs (yo) and a double decrease (sl1-k2-psso) — slip one stitch, knit the next two stitches, then pass the slipped stitch over both knit stitches. This pairing of an increase (yo) with a double decrease maintains the stitch count while creating the characteristic open, airy holes of lace fabric.
• Diagonal lace construction: The diagonal effect is achieved by shifting the starting position of the lace repeat by one stitch across every two rows. The six-row repeat cycles through three different offset positions, causing the columns of yarn overs and decreases to travel diagonally across the fabric rather than stacking vertically.
• Garter stitch borders: Three stitches at each edge of every row are worked in garter stitch (knit on both right side and wrong side), creating tidy, stable selvedge edges that prevent the lace fabric from curling and make seaming easier.
• Blocking: Optional but recommended, blocking opens up the lace motifs and evens the fabric, allowing the full beauty of the diagonal pattern to show clearly.

Stitches Used

• Knit (k) – used throughout for right side pattern rows and garter borders
• Purl (p) – used on wrong side rows within the central panel
• Yarn over (yo) – creates the lace eyelets and compensates for the decrease
• sl1-k2-psso – the signature double decrease: slip one,
