Let’s dive into the materials you’ll need and the step-by-step instructions to knit your very own Retro Rainbow Sweater!

Materials Needed

  • Yarn: Worsted weight yarn in the following colors: red, orange, yellow, green, blue, indigo, and violet.
  • Needles: US 8 (5mm) knitting needles.
  • Gauge: 18 stitches and 24 rows = 4 inches in stockinette stitch.

Step-by-Step Instructions

Back Panel

  1. Begin by casting on 90 stitches using the red yarn.
  2. Work in 1x1 ribbing (knit 1, purl 1) for 2 inches. This will create a stretchy hem.
  3. After 2 inches, switch to stockinette stitch (knit all stitches on the right side, purl all stitches on the wrong side) and continue in red for 4 inches.
  4. Change to orange yarn and knit for another 4 inches.
  5. Continue this pattern by changing colors every 4 inches, using the following sequence: yellow, green, blue, indigo, and violet. Each color should be knitted for 4 inches.
  6. Once you have completed all the stripes, bind off all stitches loosely.

Front Panel

  1. Follow the same steps as the back panel: cast on 90 stitches in red, work in 1x1 rib for 2 inches, switch to stockinette stitch in red for 4 inches, and then change colors every 4 inches following the same rainbow sequence.
  2. Once completed, bind off all stitches loosely.

Sleeves

  1. For each sleeve, cast on 50 stitches using the red yarn.
  2. Work in 1x1 ribbing for 2 inches.
  3. Switch to stockinette stitch and begin increasing: every 6th row, increase 1 stitch at each end until you have 70 stitches.
  4. Change colors every 4 inches, following the rainbow sequence as before.
  5. Once you reach the desired length, bind off all stitches loosely.

Assembly

  1. With the right sides facing each other, sew the shoulder seams of the front and back panels together.
  2. Attach the sleeves to the armholes, ensuring the seams align properly.
  3. Sew the side seams from the hem of the sweater to the end of the sleeves.
  4. Pick up stitches around the neckline using a circular needle, and work in 1x1 ribbing for 1 inch.
  5. Bind off the neckline stitches loosely to maintain stretch.

Congratulations! You have now completed your very own Retro Rainbow Sweater. Wear it proudly and enjoy the vibrant colors and cozy fit that bring back the spirit of the early 2000s!
