Materials Needed

Before you begin, gather the following supplies. The gauge and yarn weight are crucial for achieving the correct finished size of a 16-inch square pillow insert.

Yarn

• Worsted weight yarn in 5 colors (approximately 300g total):
• Color A: Deep Teal (approx. 80g)
• Color B: Soft Aqua (approx. 60g)
• Color C: Pale Mint (approx. 60g)
• Color D: Cream (approx. 60g)
• Color E: Silver Grey (approx. 40g)

Hook & Notions

• 5.0 mm (H-8) crochet hook
• Yarn needle for weaving in ends
• Scissors
• 16-inch square pillow insert (for finishing)

Gauge

16 stitches and 20 rows = 4 inches in single crochet. Always check your gauge to ensure your panel measures approximately 16 inches square. Adjust your hook size if needed to match this gauge.

Step-by-Step Instructions

This pillow is worked flat in two identical panels, then seamed together. Each panel uses a simple mosaic crochet technique with a two-row repeat. The pattern is written for a 16-inch square pillow insert. Take your time with the first few rows, and you'll quickly get into the rhythm of the pattern.

Abbreviations

• ch = chain
• sc = single crochet
• dc = double crochet
• sk = skip
• st(s) = stitch(es)
• sl st = slip stitch
• RS = right side
• WS = wrong side

Special Stitch: Mosaic Double Crochet (mdc)

This is the key stitch that creates the beautiful wave pattern. Working in front of the previous row's skipped stitches, yarn over, insert hook into the indicated stitch two rows below, yarn over and pull up a loop, yarn over and pull through two loops, yarn over and pull through the remaining two loops. This stitch is worked into the row below, not the current row, which creates the distinctive mosaic texture.
