Mosaica Coasters Crochet Pattern

This pattern combines overlay mosaic crochet with subtly slanted stitches to build a layered, tile-like design — worked one color per round using back-loop single crochet and front-loop double crochet for that crisp, raised mosaic effect.

Skill Level

Best suited for intermediate crocheters, or confident beginners ready for a new challenge.

Techniques & Stitches You'll Use

Beyond standard vertical double crochet, this pattern introduces slanted and extended double crochet (shifted one or two stitches forward or back), along with increases, decreases, and the occasional front post stitch. Every technique is explained step by step, with accompanying video tutorials — no guesswork required.
