A Designer's Tip

One of the secrets to beautiful overlay mosaic crochet is color contrast. Pairing a light yarn with a dark one helps the pattern pop and makes every geometric detail easier to see.

Don't be afraid to make it your own. Whether you choose classic black and white, vibrant colors, or a gradient palette, high contrast will always give the design its best definition.
