Materials Needed

Before you begin, gather the following supplies. Because we're using chunky yarn, the project is forgiving and fast-moving, making it perfect for cozy evenings.

Yarn

• Super Bulky Weight Yarn (Size 6) in 4 colors (approx. 200g each):
• Color A: Deep Teal
• Color B: Midnight Blue
• Color C: Emerald Green
• Color D: Soft Lavender

Tip: Choose a soft, plush yarn (like a chenille or wool blend) to enhance the cozy, cloud-like feel of the pillow.

Knitting Needles & Notions

• US Size 13 (9 mm) straight knitting needles
• Tapestry needle (for seaming and weaving in ends)
• Scissors
• Measuring tape
• 18" x 18" pillow insert (or fiberfill stuffing)

Gauge

8 stitches and 12 rows = 4 inches in stockinette stitch. While exact gauge isn't critical for a pillow, matching it ensures your panels are the correct size. If your gauge is off, adjust your needle size accordingly.

Step-by-Step Instructions

This pillow is knitted flat in two identical panels (front and back) and then seamed together. The stockinette stitch creates a smooth, V-shaped surface that beautifully showcases the crisp color transitions. Follow these detailed instructions carefully, and you'll have a gorgeous pillow in no time.

Abbreviations

• CO: Cast on
• K: Knit
• P: Purl
• St(s): Stitch(es)
• RS: Right side
• WS: Wrong side

Panel 1 (Front)

Step 1: Cast On
With Color A (Deep Teal), CO 40 stitches. Leave a 6-inch tail for weaving in later. This will create a panel approximately 18 inches wide (based on the gauge).

Step 2: First Color Block
Work in stockinette stitch for 10 rows. To do this:

• Row 1 (RS): Knit all stitches.
• Row 2 (WS): Purl all stitches.
• Repeat these two rows until you have completed 10 rows total.

Step 3: Switch to Color B (Midnight Blue)
Cut the Deep Teal yarn, leaving a 6-inch tail. Tie on the Midnight Blue yarn (or simply start knitting with the new color, leaving a tail). Work 10 rows in stockinette stitch (K on RS, P on WS).

Step 4: Switch to Color C (Emerald Green)
Cut the Midnight Blue yarn, leaving a tail. Attach Emerald Green and work 10 rows in stockinette stitch.

Step 5: Switch to Color D (Soft Lavender)
Cut the Emerald Green yarn, leaving a tail. Attach Soft Lavender and work 10 rows in stockinette stitch.

Step 6: Repeat the Color Sequence
Repeat the color sequence (Deep Teal, Midnight Blue, Emerald Green, Soft Lavender) until the piece measures 18 inches from the cast-on edge. Important: Always end with a WS row (a purl row) to ensure the next row is a RS row.

Step 7: Bind Off
Bind off all stitches loosely. To bind off: Knit the first two stitches, then use the left needle to lift the first stitch over the second and off the needle. Knit one more stitch, lift the previous stitch over, and repeat until one stitch remains. Cut the yarn, leaving a 6-inch tail, and pull it through the last loop. Weave in this tail and the cast-on tail later.

Panel 2 (Back)

Step 1: Work exactly as you did for Panel 1. Cast on 40 stitches with Deep Teal, work the same color sequence, and bind off when the panel measures 18 inches. This ensures both panels are identical in size and color placement.

Pro Tip: To ensure your panels match perfectly, count your rows as you go. Each color block is 10 rows, so you should have four 10-row blocks per 4 inches of height (based on gauge).

Finishing: Seaming and Assembly

Now for the magic moment—bringing your two panels together to form a plush pillow.

Step 1: Prepare the Panels
Lay both panels flat with the right sides facing out (the side you want to show). If you prefer a more subtle look, you can face the wrong sides out, but the stockinette's smooth V's look best on the outside.

Step 2: Whip Stitch Three Sides
Thread a tapestry needle with a long piece of matching yarn (use the color that matches the edge you're seaming, or a neutral color). Starting at one corner, whip stitch the two panels together along three sides. To whip stitch: Insert the needle through both layers from back to front, pull the yarn through, and repeat, creating a diagonal stitch along the edge. Keep the stitches even and snug, but not too tight, to avoid puckering.

Step 3: Insert the Pillow Form
Once three sides are sewn, turn the pillow cover right side out (if you seamed with wrong sides together) or simply open the fourth side. Carefully insert the 18" x 18" pillow form into the opening. Gently push the corners of the pillow form into the corners of the cover for a crisp, square shape.

Step 4: Close the Final Side
Whip stitch the fourth side closed, using the same technique. Make sure the stitches are secure and the opening is fully closed.

Step 5: Weave in All Loose Ends
Using your tapestry needle, weave in all the yarn tails from the color changes and the cast-on/bind-off edges. Thread the tail through the stitches on the wrong side of the fabric, going back and forth a few times to secure it, then trim the excess.

Optional Customization

For a more textured, rustic look, you can alternate between stockinette and garter stitch sections. For example, work 5 rows of stockinette, then 5 rows of garter (knit every row) within each color block. However, the classic stockinette stitch showcases the aurora gradient most beautifully, with its smooth, clean surface and crisp color transitions.
