Materials Needed

Before you begin, gather the following supplies. This pattern uses worsted weight yarn in three colors to create the aurora effect. The deep navy base (MC) grounds the design, while teal (CC1) and lavender (CC2) mimic the dancing lights.

• Yarn: Worsted weight yarn in 3 colors:
  • MC (deep navy) – approx 200g
  • CC1 (teal) – approx 100g
  • CC2 (lavender) – approx 100g
• Needles: US 7 (4.5mm) 16-inch circular needle and double-pointed needles (or size needed to obtain gauge)
• Gauge: 20 stitches and 26 rows = 4 inches in stockinette stitch
• Notions: Stitch markers, tapestry needle for weaving in ends, scissors

Step-by-Step Instructions

This pattern is worked in the round from the bottom up. The colorwork is created by carrying both yarns across the back of the work—don't pull them too tight, or the hat will pucker. Let's get started!

Sizes & Abbreviations

Size: Adult (fits 21-23 inch head)

Abbreviations:

• k = knit
• p = purl
• k2tog = knit two together (decrease)
• ssk = slip slip knit (decrease)
• pm = place marker
• MC, CC1, CC2 = main color, contrast color 1, contrast color 2

Ribbing

With MC, cast on 100 stitches. Join in the round, being careful not to twist. Place a marker for the beginning of the round.

Work k1, p1 ribbing for 2 inches. This creates the stretchy brim that will hug your head comfortably.

Body & Colorwork

Switch to stockinette (knit every round). Work 2 rounds in MC to establish a smooth base.

Now, begin the colorwork chart. Follow the written pattern below, carrying the unused yarn loosely behind the work. The pattern transitions from navy into teal, then into lavender, creating a gradient effect.

Round 1: *With MC k5, with CC1 k1* repeat to end.

Round 2: *With MC k4, with CC1 k2* repeat to end.

Round 3: *With MC k3, with CC1 k3* repeat to end.

Round 4: *With MC k2, with CC1 k4* repeat to end.

Round 5: *With MC k1, with CC1 k5* repeat to end.

Round 6: *With CC1 k6* repeat to end.

Round 7: *With CC1 k5, with CC2 k1* repeat to end.

Round 8: *With CC1 k4, with CC2 k2* repeat to end.

Round 9: *With CC1 k3, with CC2 k3* repeat to end.

Round 10: *With CC1 k2, with CC2 k4* repeat to end.

Round 11: *With CC1 k1, with CC2 k5* repeat to end.

Round 12: *With CC2 k6* repeat to end.

Repeat rounds 1-12 once more, then rounds 1-6 once more. This will give you a beautiful, elongated colorwork section that mimics the swirling aurora.

Continue with MC only for 3 inches, or until the piece measures 7 inches from the cast-on edge. This solid section allows the colorwork to pop and provides a clean canvas for the crown decreases.

Crown Decreases

Switch to double-pointed needles when the stitches become too tight for the circular needle. The decreases are worked every other round, creating a smooth, rounded crown.

Round 1: *K8, k2tog* repeat to end (90 stitches)

Round 2 and all even rounds: Knit all stitches.

Round 3: *K7, k2tog* repeat to end (80 stitches)

Round 5: *K6, k2tog* repeat to end (70 stitches)

Round 7: *K5, k2tog* repeat to end (60 stitches)

Round 9: *K4, k2tog* repeat to end (50 stitches)

Round 11: *K3, k2tog* repeat to end (40 stitches)

Round 13: *K2, k2tog* repeat to end (30 stitches)

Round 15: *K1, k2tog* repeat to end (20 stitches)

Round 17: *K2tog* repeat to end (10 stitches)

Cut the yarn, leaving a long tail (about 12 inches). Thread the tail through a tapestry needle, then pass it through the remaining 10 stitches. Pull tight to close the hole, and secure with a knot. Weave in all ends carefully, especially in the colorwork section, to keep the inside neat.

Finishing

Block lightly by wetting the hat and laying it flat to dry. This will even out the stitches and relax the colorwork. Fold up the ribbing for a classic look, or leave it straight for a slouchier style. Your Aurora Boreal Beanie is ready to wear!

This pattern is a fantastic way to practice stranded colorwork while creating a wearable piece of art. The gradient effect is forgiving—even if your tension is slightly uneven, the swirling colors will hide it beautifully. Enjoy your celestial creation!
