Resonance Square | Overlay Mosaic Crochet Pattern

Explore the geometry of Resonance, an overlay mosaic crochet square featuring a repeating diamond motif and a balanced, symmetrical design. Worked in the round from the center outward, the pattern develops in a clear, predictable sequence, making it especially enjoyable for crocheters who like to visualize how each round contributes to the finished motif. Settle into the repeating stitches and watch the diamonds emerge as your square grows.

The finished square measures approximately 12 × 12 inches (30 × 30 cm), making it a versatile building block for blankets, cushions, bags, garments, and other modular crochet projects.

Color Tip

Want to bring more color into your mosaic crochet? The large diamond shapes in Resonance are well suited to variegated yarn used as the background, adding several shades without frequent color changes. For designs with smaller motifs, you can also experiment with multiple background colors arranged in a gradient. Whichever palette you choose, keep a strong contrast between the background and the mosaic pattern so the geometric shapes remain distinct and easy to see.
