Figure 3. Double Crochet
Double crochet. ([Figure 3]). Having a stitch on needle, insert hook in work, take up thread and draw through, giving you two stitches on the needle; take up thread and draw through the two stitches. The abbreviation is d c. There are many variations of the double-crochet stitch; the slipper-stitch, or ribbed stitch, is formed by taking up the back horizontal loop or vein of each stitch in preceding row. A quite different effect is given when the hook is inserted under both loops.
