Color Tip

Overlay mosaic crochet relies on contrast to create its striking effect. For the clearest stitch definition, choose one light and one dark color rather than two shades of similar value. The stronger the contrast, the more the geometric pattern will shine. Feel free to experiment with gradients or bold color combinations to create your own unique version.
