Single Crochet in Third Loops Only (sc3rd)

A "single crochet in the third loop only" refers to a crochet technique where you work a single crochet stitch into a specific part of the stitch, rather than the traditional front and back loops at the top of the stitch. When instructed to single crochet into the third loops only, insert your hook into this loop (ignoring the front and back loops). This creates a braided look on the opposite side of your work.
