Materials Needed

Before you cast on, gather your supplies. This project uses worsted weight yarn, which is perfect for creating a warm, durable fabric with excellent stitch definition.

• Yarn: Worsted weight yarn in 4 shades: deep teal, sky blue, soft lavender, and pale pink (approx. 1200-1500 yards total).
• Needles: US 8 (5 mm) circular needles 24-32 inches long, and US 8 double-pointed needles for the sleeves.
• Notions: Stitch markers, stitch holders or waste yarn, tapestry needle for weaving in ends.
• Gauge: 18 stitches and 24 rows = 4 inches in stockinette stitch. Always check your gauge to ensure the correct fit!

Step-by-Step Instructions

This pattern is knit from the top down, meaning you start at the neck and work your way to the hem. The seamless construction minimizes finishing work and allows the gradient to flow beautifully. Let’s get started!

Knitting the Yoke

The yoke is where the magic begins. We'll start with the deep teal and create the initial increases that shape the shoulders.

1. Cast On & Ribbing: With deep teal, CO 72 (80, 88) sts. Join in the round, being careful not to twist. PM at the beginning of the round. Work K2, P2 ribbing for 1 inch.
2. Switch to Stockinette: Knit every round for the stockinette stitch body.
3. Increase Round 1: *K8 (9, 10), M1R* repeat to end of round – 81 (90, 99) sts. Knit 3 rounds even.
4. Increase Round 2: *K9 (10, 11), M1R* repeat to end – 90 (100, 110) sts. Knit 3 rounds even.
5. Color Transition & More Increases: Switch to sky blue. Continue increasing every 4th round, adding 9 (10, 11) sts each time, until you have 144 (160, 176) sts. Tip: To keep the increases evenly spaced, simply add one more knit stitch before the M1R in each subsequent increase round.
6. Work Even: Once you have the required number of stitches, work even in stockinette for 2 inches.

Dividing for Body and Sleeves

Now we’ll separate the sleeve stitches from the body, creating the armholes.

1. Knit 22 (25, 28) sts for the back.
2. Place the next 28 (30, 32) sts on a stitch holder or waste yarn for the sleeve.
3. CO 6 (8, 10) sts underarm.
4. Knit 44 (50, 56) sts for the front.
5. Place the next 28 (30, 32) sts on a holder for the second sleeve.
6. CO 6 (8, 10) sts underarm.
7. Knit the remaining 22 (25, 28) sts for the back. Total body sts: 100 (116, 132).

Knitting the Body

With the sleeves resting on their holders, we’ll focus on the main body of the sweater.

1. Continue in Stockinette: Knit every round. After 4 inches, switch to soft lavender. After 8 inches, switch to pale pink.
2. Work to Length: Continue in stockinette until the body measures 10 (12, 14) inches from the underarm.
3. Bottom Ribbing: Work K2, P2 ribbing for 1 inch. Bind off loosely to maintain a stretchy edge.

Knitting the Sleeves

Time to bring the sleeves to life. We’ll work them in the round on double-pointed needles.

1. Pick Up Stitches: Place the sleeve sts from the holder onto DPNs. Pick up and knit 6 (8, 10) sts from the underarm cast-on edge. PM to mark the beginning of the round.
2. Shape the Sleeve: Knit in stockinette, decreasing 1 st each side of the marker every 6th round until 30 (34, 38) sts remain. To decrease: K2tog before the marker, SSK after the marker.
3. Color Changes: Switch to lavender after 4 inches, and to pale pink after 8 inches.
4. Cuff Ribbing: Work K2, P2 ribbing for 1 inch. Bind off loosely. Repeat for the second sleeve.

Finishing Touches

You’re almost there! The final steps will give your sweater a professional, polished look.

1. Weave in Ends: Use your tapestry needle to carefully weave in all loose yarn ends on the inside of the sweater.
2. Block to Size: This is a crucial step. Wet block your sweater by soaking it in lukewarm water with a little wool wash, gently squeezing out excess water, and laying it flat to dry on a towel. Gently shape it to the finished measurements. This will even out the stitches and enhance the drape of the gradient.

And there you have it—your very own Aurora Boreal Sweater! This project is a beautiful way to explore colorwork and seamless construction. The gradient effect is truly mesmerizing, and the cozy, oversized fit makes it a wardrobe staple you’ll reach for again and again. Happy knitting!
