In this photo, Sigoni Macaroni is explaining how you should be counting your crochet stitches and rows using a swatch of half double crochet. Pictured is a yarn swatch consisting of four rows of half double crochet stitches. There are nine stitches in each row. The photo is explaining that the turning chain 2 at the beginning of the row counts as a stitch. There are also stitch markers showing what the front and back of a half double crochet stitch looks like.
