Materials Needed

Before you begin, gather the following materials. All are readily available at your local yarn shop or online.

Yarn

• Worsted weight yarn in three colors:
  • Spearmint (MC) – approx. 300g (main color)
  • Cream (CC1) – approx. 150g (contrast color 1)
  • Silver Sage (CC2) – approx. 100g (contrast color 2)

Needles & Notions

• US 8 (5mm) knitting needles (or size needed to achieve gauge)
• Tapestry needle for weaving in ends and seaming
• Stitch markers (optional, but helpful)

Gauge

18 stitches and 24 rows = 4 inches in stockinette stitch (after blocking). Gauge is important for the final size, so be sure to knit a swatch first.

Step-by-Step Instructions

This cowl is worked flat in a corner-to-corner (C2C) technique using increases and decreases to create a square, then folded and seamed into a cowl. The star motif is created using intarsia colorwork. Follow along carefully, and you'll have a beautiful cowl in no time.

Abbreviations

• k = knit
• p = purl
• kfb = knit front and back (increase)
• k2tog = knit two together (decrease)
• st(s) = stitch(es)
• MC = main color (Spearmint)
• CC1 = contrast color 1 (Cream)
• CC2 = contrast color 2 (Silver Sage)

Section 1: Increase (Make a Triangle)

We'll start by increasing stitches at the beginning of each row to form a triangle. This is the first half of your square.

1. Row 1: With MC, kfb into the first stitch (2 sts).
2. Row 2: kfb, k to end (3 sts).
3. Row 3: kfb, k to end (4 sts).
4. Continue in this manner, increasing by 1 stitch at the beginning of every row (kfb on first stitch, then knit to end), until you have 30 stitches on your needle.
5. End with a wrong-side row (purl row if you're working in stockinette, but here we're working in garter stitch, so just knit all stitches).

Tip: If you prefer a larger cowl, you can continue increasing to 40 or 50 stitches. Just adjust the chart accordingly.

Section 2: Work Even (Rectangle Base)

Now we'll work even without increases for 30 rows, maintaining the same stitch count. On the first row of this section, begin the star motif using intarsia. Follow the chart below—each square equals 1 stitch. Read right-side rows from bottom right to top left, and wrong-side rows from top left to bottom right.

Star Motif Chart (30 stitches wide, 30 rows tall)

Important: For wrong-side rows, purl the same color pattern, but read the chart from left to right (i.e., mirror the right-side row).

How to work intarsia: When you change colors, twist the new yarn around the old yarn to avoid holes. Use separate balls or bobbins for each color section. Don't carry yarn across the back—this is intarsia, not fair isle.

After completing the 30 even rows, you will have a square with a star motif in the center. The star's outer points are cream (CC1), and the inner diamond is silver sage (CC2), all set against the spearmint (MC) background.

Section 3: Decrease (Make a Triangle)

Now we'll decrease 1 stitch at the beginning of every row to form the second triangle, completing the square.

1. Row 1: k2tog, k to end (29 sts).
2. Row 2: k2tog, k to end (28 sts).
3. Continue in this manner until you have 1 stitch left.
4. Cut yarn and pull through the last loop to secure.

Note: You'll notice the decrease rows naturally form a diagonal line that mirrors the increase section, creating a perfect square.

Finishing

Now for the fun part—turning your square into a cowl!

1. Block the square flat to even out the stitches and set the intarsia work. Pin it to the correct dimensions and let it dry completely.
2. Fold the square in half diagonally to form a triangle. The two opposite corners should meet.
3. Fold again to form a cowl shape—you want the two folded edges to align, creating a double-layer tube.
4. Seam the two edges together using mattress stitch (or whip stitch) along the open side. Leave a small opening (about 3-4 inches) for turning.
5. Turn the cowl right side out through the opening.
6. Seam the remaining opening closed using the same mattress stitch, then weave in all ends with your tapestry needle.

Optional Embellishments

Add a decorative button or a small crocheted flower at the seam for extra charm. This is a lovely way to personalize your cowl or use up leftover yarn.

Tips for Success

• Count your stitches after each increase or decrease row to ensure accuracy.
• Use bobbins for intarsia to keep yarns from tangling.
• Block before seaming—this makes the edges easier to align and the final cowl more polished.
• Choose soft yarn for maximum coziness. A wool-blend or acrylic-wool mix works beautifully.
