Materials Needed

Before you begin, gather the following supplies. Using the exact materials will ensure your pillow matches the intended size and texture.

• Yarn: Super bulky weight yarn (size 6) in three colors: deep teal, soft lavender, and pale mint (approx. 200g each). This is roughly 3 skeins of 200g each, or 6 skeins of 100g each, depending on the brand.
• Knitting Needle: US 13 (9 mm) circular knitting needle with a 24-inch cable. The circular needle is essential to accommodate the width of the panel.
• Cable Needle: A standard cable needle (or a double-pointed needle of similar size) for the C4F and C4B maneuvers.
• Extras: Stitch markers (2), tapestry needle for seaming, scissors, and a 12x12 inch pillow form.
• Optional: Three large wooden buttons (approx. 1.5 inches) for a decorative closure.

Gauge: 8 stitches and 10 rows = 4 inches in stockinette stitch. Always knit a gauge swatch to ensure your pillow is the correct size. If your gauge is off, adjust your needle size accordingly.

Step-by-Step Instructions

This pillow is knitted as a single flat panel and then seamed, with an envelope closure on the back. The front and back of the panel are identical, so you only knit one large piece. Follow these detailed instructions carefully, and you'll have a beautiful pillow in no time.

Knitting the Panel

Cast On: With your deep teal yarn, cast on 40 stitches using your preferred method (long-tail cast on works well).

Rows 1-4 (Garter Stitch Border): Knit all 40 stitches for 4 rows. This creates a neat, sturdy edge that will frame your pillow.

Row 5 (Right Side - Begin Cable Pattern): Knit 4 stitches (this is your garter border), place a stitch marker, work the cable pattern across the next 32 stitches, place a second stitch marker, and knit the final 4 stitches. The markers will help you keep track of the cable section.

The Cable Pattern (Worked over 32 stitches)

This pattern creates bold, twisted ropes. Repeat these 8 rows continuously. Pay close attention to the C4F and C4B instructions.

• Row 1 (Wrong Side): P2, K4, P2, K4, P2, K4, P2, K4, P2, K4, P2. (Total 32 stitches)
• Row 2 (Right Side): K2, P4, K2, P4, K2, P4, K2, P4, K2, P4, K2.
• Row 3 (Cable Row - Right Side): P2, C4F (slip 2 stitches to cable needle, hold in front, knit next 2 stitches, then knit 2 from cable needle), P2, C4B (slip 2 stitches to cable needle, hold in back, knit next 2 stitches, then knit 2 from cable needle), P2, C4F, P2, C4B, P2, C4F, P2, C4B, P2. (This completes the cable twists across the row).
• Row 4: Same as Row 2 (K2, P4, K2, P4, K2, P4, K2, P4, K2, P4, K2).
• Rows 5-6: Repeat Rows 1 and 2.
• Rows 7-8: Repeat Rows 1 and 2.

Important: After completing Row 8, you have finished one full 8-row repeat. Continue repeating these 8 rows until you have knitted 10 inches of fabric in deep teal. This will be approximately 25 rows of the pattern, but always measure your work to be sure.

Color Transitions

Once your deep teal section measures 10 inches, you will switch colors. Do not cut the teal yarn yet—you can carry it up the side or weave in ends later. For a cleaner look, cut the yarn leaving a 6-inch tail and weave it in.

Switch to Soft Lavender: Join your soft lavender yarn and continue the exact same cable pattern (Rows 1-8 repeated) for another 10 inches. Remember to maintain the 4-stitch garter border on each side.

Switch to Pale Mint: After the lavender section measures 10 inches, join your pale mint yarn and knit the final 10 inches of the cable pattern. Once you reach 10 inches in mint, you will finish the panel.

Finishing the Panel

Final Border: With pale mint, knit 4 rows of garter stitch (knit all stitches) to mirror the bottom border.

Bind Off: Bind off all 40 stitches loosely. A loose bind-off is crucial to prevent the edges from pulling. You can use a standard bind-off but ensure you don't pull the yarn too tight, or use a stretchy bind-off method like "Jeny's Surprisingly Stretchy Bind-Off" for best results.

Seaming and Assembly

Now that your panel is complete, it's time to transform it into a pillow. Lay the panel flat on a table with the right side facing up. The bottom (teal) edge should be at the bottom.

Step 1: Fold the Bottom Pocket. Take the bottom 6 inches of the panel (the teal section) and fold it upward, so the teal is on the inside of the fold. This will be the front pocket that holds the pillow form.

Step 2: Fold the Top Flap. Take the top 8 inches of the panel (the mint section) and fold it downward, over the teal pocket. The mint flap should overlap the teal pocket by about 2 inches. This creates the envelope closure.

Step 3: Sew the Side Seams. With your tapestry needle and a length of matching yarn (use the pale mint or a neutral color), sew the side seams together. You will be sewing through all layers: the bottom pocket, the back of the pillow, and the top flap. Start at the bottom edge and sew up to the top of the flap. Leave the top edge of the flap open—this is where you'll insert the pillow form. Use a whip stitch or mattress stitch for a sturdy seam.

Step 4: Turn Right Side Out. Carefully turn the pillow right side out through the opening at the top of the flap. Gently push out the corners to ensure they are sharp.

Step 5: Insert Pillow Form. Insert your 12x12 inch pillow form through the opening. The flap will naturally fall over the pocket, creating a seamless, professional look.

Step 6 (Optional): Add Buttons. For a secure closure and a decorative touch, you can add three large wooden buttons. Sew the buttons onto the outside of the mint flap. Then, on the teal pocket (which is now on the inside), create corresponding buttonholes or simply sew loops of yarn to catch the buttons. This is an optional step—the envelope closure works fine on its own.

Your Aurora Borealis Chunky Throw Pillow is now complete! The gradient of deep teal, soft lavender, and pale mint mimics the ethereal beauty of the northern lights, while the chunky cables add depth and texture.
