Mosaic crochet (also called overlay mosaic crochet or just overlay crochet) is a technique that uses BLO (back loops only) single crochet stitches and FLO (front loops only) dropped double crochet stitches to create intricate designs. In fact, you would crochet textured stitches that lay over (hence the name overlay crochet) previous row stitches. As a result, it creates very intricate patterns reminiscent of tapestry or cross-stitching.
