Knitted flat in soft, chunky worsted weight yarn, this pattern is perfect for intermediate beginners looking to expand their skills. The clean lines, cozy fit, and beautiful color transitions make it a joy to knit and an even greater joy to gift. Let's dive into creating this handmade treasure together!

Materials Needed for Your Aurora Sweater

Before we cast on, let's gather our supplies. This pattern is all about preparation, so having everything ready will make your knitting experience smooth and enjoyable. Here’s what you'll need:

  • Yarn: Worsted weight (Category 4) yarn in 4 colors. The pattern uses approximately 300-400g total, depending on the size you choose.
    • Color A (Sky Blue): For the main body.
    • Color B (Cream): For the contrasting color block.
    • Color C (Coral): For the sleeves.
    • Color D (Mustard): For the neckband.
  • Needles: US 7 (4.5mm) knitting needles. You can use straight needles or a circular needle for flat knitting, whichever you prefer.
  • Notions: Stitch markers, a tapestry needle for weaving in ends and seaming, and scissors.
  • Gauge: 20 stitches x 26 rows = 4 inches in stockinette stitch (knit one row, purl one row). Always take time to check your gauge to ensure the correct fit!

Step-by-Step Instructions: Knitting the Aurora Sweater

This pattern is worked in pieces and seamed together, which makes it very manageable. We'll start with the back, then the front, sleeves, and finally the finishing touches. Let's get those needles clicking!

Sizes & Abbreviations

SIZES: 15 (12 months, 3 years, 7 years) – finished chest: 20 (22, 24, 26) inches.

ABBREVIATIONS:

  • K = Knit
  • P = Purl
  • K2tog = Knit two together (decrease)
  • P2tog = Purl two together (decrease)
  • St(s) = Stitch(es)
  • RS = Right side
  • WS = Wrong side

NOTE: The sweater is worked flat in stockinette stitch (K on RS, P on WS) with a garter stitch border (K every row) for a clean, non-curling edge.

Knitting the Back

  1. With Color A, cast on 50 (55, 60, 65) sts.
  2. Work 6 rows in garter stitch (knit every row). This forms the bottom hem.
  3. Switch to stockinette stitch (Row 1 RS: K, Row 2 WS: P).
  4. Work even in stockinette until the piece measures 8 (9, 10, 11) inches from the cast-on edge, ending with a WS row.
  5. Shape shoulders: Bind off 5 (6, 6, 7) sts at the beginning of the next 2 rows, then bind off 5 (6, 7, 7) sts at the beginning of the following 2 rows.
  6. Bind off the remaining 30 (31, 34, 37) sts for the back neck. Set this piece aside.

Knitting the Front (with Color Blocks)

  1. Cast on the same number of sts as the back with Color A.
  2. Work 6 rows in garter stitch.
  3. Switch to stockinette stitch and work 2 rows even.
  4. Begin Color Block Pattern:
    • Row 3 (RS): With Color A, K 25 (28, 30, 33) sts. Join Color B, and K the remaining 25 (27, 30, 32) sts.
    • Continue in stockinette, working each side with its respective color. Important: Twist the yarns together at the color change on every row to avoid creating holes in your work.
  5. Work even in this color pattern until the piece measures 6 (7, 8, 9) inches from the cast-on edge, ending with a WS row.
  6. Shape Neck:
    • On the next RS row, work across the first 20 (22, 24, 26) sts. Join a new ball of yarn, bind off the center 10 (11, 12, 13) sts, and work to the end of the row. You will now be working both sides of the neck separately.
    • Working both sides at the same time with separate balls of yarn, decrease 1 st at each neck edge every RS row 3 times. This shapes the neckline curve.
    • Continue even on the remaining 17 (19, 21, 23) sts on each side until the piece measures the same as the back to the shoulder.
  7. Shape shoulders: Bind off for the shoulders exactly as you did for the back.

Knitting the Sleeves (Make 2)

  1. With Color C, cast on 30 (34, 38, 42) sts.
  2. Work 6 rows in garter stitch for the cuff.
  3. Switch to stockinette stitch.
  4. Increase row (RS): K1, M1 (make one), knit to the last st, M1, K1. (See note below for M1).
  5. Repeat this increase row every 6th row until you have 40 (46, 52, 58) sts on your needle.
  6. Work even in stockinette until the sleeve measures 7 (8, 9, 10) inches from the cast-on edge.
  7. Bind off all sts loosely. Repeat for the second sleeve.

Note on M1 (Make One): To make one stitch, pick up the horizontal bar between the stitch you just knit and the next stitch, place it on the left needle, and knit it through the back loop. This creates an invisible increase.

Finishing and Assembly

  1. Sew Shoulder Seams: Using your tapestry needle and a matching yarn, sew the shoulder seams of the front and back pieces together.
  2. Set in Sleeves: Pin the center of the sleeve cap to the shoulder seam. Pin the rest of the sleeve cap to the armhole edge, easing in any fullness. Sew the sleeves into the armholes.
  3. Sew Side and Sleeve Seams: With the right sides together, sew the side seams of the sweater and continue down to sew the sleeve seams in one continuous line.
  4. Neckband: With Color D, pick up and knit 60 (66, 72, 78) sts evenly around the neck edge. Work 4 rows in garter stitch. Bind off loosely.
  5. Weave in Ends: Carefully weave in all loose yarn ends with your tapestry needle to give your sweater a professional finish.
  6. Blocking: Gently block your sweater to the specified measurements. This will even out the stitches and give the color blocks a crisp, polished look.

And there you have it—a beautiful, cozy Aurora Color Block Sweater! The combination of the soft sky blue, cream, coral, and mustard creates a stunning visual that's both modern and timeless. This pattern is a wonderful way to practice color work and garment construction. I can't wait to see your little one snuggled up in this handmade hug. Happy knitting!
