Materials Needed

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

• Yarn: Worsted weight cotton yarn in 4 colors—Cream (A), Sage Green (B), Terracotta (C), and Mustard Yellow (D). You'll need approximately 800g total for one 24x36 inch panel. (For two panels, double the yarn.)
• Needles: US 7 (4.5 mm) knitting needles
• Notions: Tapestry needle for weaving in ends, stitch markers (optional but helpful), and a tape measure
• Gauge: 20 stitches and 28 rows = 4 inches in stockinette stitch (knit on right side, purl on wrong side). Always check your gauge to ensure the correct finished size.

Step-by-Step Instructions

This pattern creates a single curtain panel measuring approximately 24 inches wide by 36 inches long. For a standard window, make two panels. The design is built from a grid of geometric squares, each featuring a unique stitch pattern, joined seamlessly as you knit. Follow along carefully, and you'll have a gorgeous curtain in no time.

Panel Construction Overview

The panel is knit in one piece from the bottom up. You'll work a series of square motifs in a checkerboard layout, using intarsia (separate balls of yarn for each color section) and textured stitches. The pattern alternates between two main square designs—a diamond lattice and a chevron zigzag—and switches colors every 24 rows to create a vibrant mosaic.

Foundation Row

With Color A (Cream), cast on 120 stitches. Knit 6 rows in garter stitch (knit every row) to create the bottom border. This gives a sturdy, neat edge.

Rows 1–24: First Set of Squares

Row 1 (Right Side): With Color A, K6 (border), then begin the first square motif: *K24 in Color A, switch to Color B (Sage Green) and K24, rep from * across the row, ending with K6 in Color A. You'll have 120 stitches total, divided into six 24-stitch sections (including the borders).

Rows 2–24: Work in stockinette stitch (knit on right side, purl on wrong side) following the color chart below. Each 24-stitch section is a square with its own pattern:

• Square 1 (Color A – Diamond Pattern): On right-side rows, work: K10, K2tog, YO, K2, YO, SSK, K8. On wrong-side rows, purl all stitches. Repeat this sequence across the 24 stitches of this square.
• Square 2 (Color B – Chevron Pattern): On right-side rows, work: K2, *K2tog, K4, YO, K1, YO, K4, SSK, K2, rep from * across the 24 stitches. On wrong-side rows, purl all stitches.

Continue alternating these two square patterns across the row, using Color A for the diamond squares and Color B for the chevron squares. Remember to keep the 6 border stitches in garter stitch (knit every row) on both edges.

Rows 25–48: Switch Square Positions

Now, swap the patterns: Work the diamond pattern in Color B (Sage Green) and the chevron pattern in Color A (Cream). This creates a checkerboard effect. Continue in stockinette stitch, following the same stitch sequences as above but with the colors switched. Keep the 6-stitch borders in Color A throughout.

Rows 49–72: Introduce New Colors

For the next two rows of squares, bring in Color C (Terracotta) and Color D (Mustard Yellow). Use the same diamond and chevron patterns, but assign the colors as follows:

• Diamond squares: Color C (Terracotta)
• Chevron squares: Color D (Mustard Yellow)

Work in stockinette stitch, alternating the two patterns across the row as before. Keep the borders in Color A.

Rows 73–96: Repeat the First Set

To complete the panel, repeat the first two rows of squares (Rows 1–24) using Colors A and B. This creates a balanced, symmetrical design with the cream and sage squares at both the bottom and top of the panel.

Top Border

With Color A (Cream), knit 6 rows in garter stitch (knit every row) for the top border. Bind off loosely to maintain a flexible edge that won't pucker.

Finishing Touches

Weave in all loose ends with a tapestry needle, being careful to secure them on the wrong side of the work. Block the panel to the specified dimensions (24x36 inches) by pinning it to a blocking mat and steaming or misting with water. Allow it to dry completely.

To hang, sew a fabric curtain rod pocket to the top edge or use clip rings. The open stitches of the geometric squares will create beautiful light patterns when hung in a window, casting intricate shadows that change throughout the day.

Tips for Success

• Manage your yarn: When switching colors within a row, use separate balls or bobbins for each color section to avoid tangling. Twist the yarns at each color change to prevent holes.
• Check your gauge: A proper gauge ensures your panel fits your window perfectly. If your gauge is off, adjust your needle size accordingly.
• Block generously: Cotton yarn benefits from blocking to even out stitches and achieve the final dimensions. Don't skip this step!

With these detailed instructions, you'll create a stunning Prism Cascade Window Panel that adds warmth, texture, and artistry to your home. Happy knitting!
