Materials Needed

Before you begin, gather the following supplies to ensure a smooth knitting experience:

Yarn

• Worsted weight cotton or cotton-blend yarn in three shades:
  • Sand (A) – warm sandy beige
  • Driftwood (B) – muted taupe
  • Seafoam (C) – soft green
• Approximately 250g total (roughly 85g of each color)

Needles & Notions

• US 8 (5mm) knitting needles – straight or circular (for comfort with larger projects)
• Tapestry needle for weaving in ends and seaming
• 18-inch (45cm) pillow form for the finished cover
• Stitch markers (optional, but helpful for keeping track of pattern repeats)

Gauge

18 stitches and 24 rows = 4 inches (10cm) in stockinette stitch. Always knit a gauge swatch to ensure your finished pillow fits the pillow form properly. Adjust needle size if needed to match gauge.

Step-by-Step Instructions

This pillow cover is knitted flat in one piece with a repeating ripple pattern, then seamed and finished with a simple envelope closure. Follow these detailed instructions carefully for a flawless result.

Abbreviations

• K = knit
• P = purl
• K2tog = knit two stitches together (right-leaning decrease)
• SSK = slip, slip, knit (left-leaning decrease)
• YO = yarn over (increase creating an eyelet)
• RS = right side
• WS = wrong side

Pattern Notes

• The ripple pattern is a multiple of 12 stitches + 2 edge stitches.
• Use a slip stitch edge for neat, professional-looking seams.
• Change colors every 8 rows in this order: A, B, C, B, A, B, C, B (repeat for desired length).

Cast On

With Color A, cast on 86 stitches loosely. A loose cast-on is essential to prevent the bottom edge from pulling and to maintain the ripple pattern's drape. Consider using a larger needle for the cast-on row or a stretchy cast-on method like the long-tail cast-on.

Ripple Pattern

Work in rows as follows, changing colors every 8 rows in the order noted above. The pattern creates a beautiful undulating ripple effect that mimics sand dunes.

Row 1 (RS): Slip 1 knitwise, K1, *K2tog, K2tog, YO, K1, YO, K1, YO, K1, YO, K2tog, K2tog, repeat from * to last 2 stitches, K2.

Row 2 (WS): Slip 1 purlwise, Purl all stitches to last stitch, P1.

Row 3: Slip 1 knitwise, K1, *K2tog, K2tog, YO, K1, YO, K1, YO, K1, YO, K2tog, K2tog, repeat from * to last 2 stitches, K2.

Row 4: Repeat Row 2.

Row 5: Repeat Row 3.

Row 6: Repeat Row 2.

Row 7: Repeat Row 3.

Row 8: Repeat Row 2.

Repeat Rows 1-8, changing colors as noted, until the piece measures approximately 36 inches (91cm) from the cast-on edge, ending with a WS row. This length allows for the pillow form to fit snugly with a slight overlap for the envelope closure.

Bind off loosely in pattern. To maintain the ripple effect, bind off using a stretchy method or bind off in pattern (knitting the knits and purling the purls as they appear).

Understanding the Ripple Pattern

If you're new to ripple patterns, here's what's happening: the K2tog decreases create the "valleys" of the ripple, while the YO increases paired with the center K1 stitches create the "peaks." Each 12-stitch repeat contains 4 decreases and 4 increases, keeping the stitch count consistent throughout. The result is a gentle wave that's both tactile and visually stunning.

Finishing

Follow these steps to complete your pillow cover:

1. Weave in all loose ends using your tapestry needle, being careful to weave them in on the wrong side of the work.
2. Fold the knitted rectangle in half with RS together, matching the cast-on and bind-off edges. The piece should now measure approximately 18 inches wide by 18 inches tall.
3. Sew the side seams using a mattress stitch or whip stitch, leaving a 10-inch (25cm) opening in the middle of one side for the pillow form. This opening should be large enough to easily insert the pillow form.
4. Turn the cover RS out through the opening, gently pushing out the corners for a crisp finish.
5. Insert the pillow form through the opening, fluffing it to fill the corners of the cover.
6. Hand-stitch the opening closed using a mattress stitch for an invisible seam. Take small, even stitches to ensure a secure closure.

Optional Embellishment

For extra texture and visual interest, add a few hand-stitched decorative stitches along the ripple valleys using a contrasting yarn. This subtle detail catches the light and adds depth to the finished piece. Use a simple running stitch or backstitch, following the natural curves of the pattern.

Tips for Success

• Count your stitches regularly – the ripple pattern is rhythmic but easy to lose track of. Place stitch markers between each 12-stitch repeat to help you stay on track.
• Keep your tension consistent – especially when changing colors. Avoid pulling the yarn too tight when switching colors to prevent puckering.
• Block your piece before seaming – wet block or steam block the knitted rectangle to even out the stitches and set the ripple pattern. This makes seaming easier and gives a more professional finish.
• Use a pillow form slightly larger than your cover – this ensures a plump, full look. An 18-inch form in an 18-inch cover creates a snug, tailored appearance.

Care Instructions

To keep your Drifting Dune Pillow looking its best, hand wash in cool water with a gentle detergent. Lay flat to dry, reshaping as needed. Avoid wringing or twisting, which can distort the ripple pattern. If using a cotton-blend yarn, you may be able to machine wash on a gentle cycle in a mesh bag, but always check your yarn's care label first.

This pattern is a wonderful way to practice color changes and texture work while creating a beautiful, functional piece for your home. The Drifting Dune Throw Pillow makes a thoughtful handmade gift or a stunning addition to your own coastal-inspired decor. Enjoy the rhythmic knitting and the satisfaction of watching your sand dune ripple come to life!
