Crochet: hdc (half double crochet)

In crochet, “hdc” stands for half double crochet — a stitch that’s taller than a single crochet (sc) but shorter than a double crochet (dc).

It’s one of the most popular stitches because it works up quickly, gives a smooth, flexible fabric, and is easy to learn — great for blankets, scarves, hats, and clothing!
