How to crochet front and back post stitches: raised ribbing

Instead of the top of the stitch, work around its post: from the front for a front-post double crochet (FPdc), so the post stands forward, and from the back for a back-post double crochet (BPdc). Alternated, they make ribbing.

2 loops on the hook

Step 1 Yarn over. Insert the hook from the front, behind the post of the next stitch below, and out to the front again.

US / UK US FPdc and BPdc = UK FPtr and BPtrAny number of stitches; ribbing alternates FPdc and BPdc, often 1 and 1 or 2 and 2.

Before you start: Double crochet

Make one front-post double crochet

  1. Yarn over. Insert the hook from the front, behind the post of the next stitch below, and out to the front again.
  2. Yarn over and pull up a loop around the post: three loops are on the hook.
  3. Yarn over and draw through two loops.
  4. Yarn over and draw through the last two loops. The new stitch stands out on the side facing you.

Back post and ribbing

For a back-post double crochet (BPdc), insert from the back, in front of the post and out to the back again, then finish the same way. The stitch sinks away from you.

Ribbing: on a row of double crochet, chain 2 and turn, then repeat [FPdc around the next post, BPdc around the next post] across, ending with a double crochet in the last stitch. On the next rows, work FPdc around the posts that stand toward you and BPdc around those that sink, so the ribs line up.

Use it in

Hat brims and cuffs, the waffle throw (made with front-post stitches) and cabled blankets. Post stitches use more yarn and pull the fabric in, so a ribbed brim is narrower than plain rows of the same count.
