Materials Needed

  • Yarn: Fingering weight, 100% cotton, in shades of teal, seafoam, and luminescent white
  • Needles: US 4 (3.5mm) knitting needles
  • Gauge: 24 stitches and 32 rows = 4 inches in stockinette stitch
  • Stitch markers (optional, but helpful)
  • Tapestry needle for weaving in ends
  • Measuring tape for checking dimensions

Step-by-Step Instructions

  1. Cast On: Begin by casting on 120 stitches using the long-tail cast-on method. Ensure that you join in the round carefully to avoid twisting the stitches. Place a stitch marker to indicate the beginning of the round.
  2. Ribbing: Work in k1, p1 ribbing for 1 inch. This creates a stretchy edge that will help the sweater fit comfortably.
  3. Body: Switch to stockinette stitch by knitting every round. Continue working in stockinette stitch until the body measures 12 inches from the cast-on edge.
  4. Divide for Sleeves: To create the armholes, bind off 10 stitches at the beginning of the next two rounds. You will now have 100 stitches remaining on your needle.
  5. Front and Back: Work flat in stockinette stitch for 8 inches, making sure to end with a purl row to create a nice edge for the shoulders.
  6. Shoulder Shaping: For the shoulder shaping, bind off 5 stitches at the beginning of the next 4 rows. This will create a gentle slope for the shoulders.
  7. Neckline: After completing the shoulder shaping, bind off the remaining 60 stitches. This will form the neckline of your sweater.
  8. Sleeves: To create the sleeves, pick up 60 stitches around the armhole. Make sure to evenly distribute the stitches. Work in stockinette stitch for 8 inches.
  9. Ribbing for Sleeves: Switch to k1, p1 ribbing for 1 inch at the end of the sleeves. This will give the sleeves a finished look. Bind off all stitches loosely to maintain elasticity.
  10. Finishing: Weave in all loose ends using a tapestry needle. Finally, block the sweater to measurements to ensure it has the perfect shape and drape.

Congratulations! You have now completed your Bioluminescent Tidepool Summer Sweater. Enjoy wearing your handmade creation and embrace the beauty of your craftsmanship!
