Back Post Half Double Crochet

Step-by-step: How to make one BPhdc (US terms)

1. Yarn over (yo).
2. Insert the hook around the post of the indicated stitch from back to front and back again, so the hook encircles the vertical post (not the top loops).
3. Yarn over and pull up a loop, you’ll have 3 loops on the hook.
4. Yarn over and draw through all three loops. One loop remains on the hook ,BPhdc complete.

Practice swatch: 8-row rib sample

Chain 18.

Row 1: Hdc in 2nd ch from hook and across (17 hdc). Turn.

Row 2: Ch 2 (turning chain), *BPhdc in each stitch across*. Turn.

Row 3: Ch 2, Hdc across. Turn.

Repeat Rows 2–3 for a ribbed fabric.

Result: alternating BPhdc and regular hdc rows creates a structured, reversible rib.

Common mistakes & troubleshooting

• Hook goes into top loops (result: regular hdc).Reposition so you can feel the vertical post and slip the hook around it.
• Loose ribs: keep even tension when pulling up the loop; try one hook size smaller for neater ribs.
• Lost stitch count at edges: use a stitch marker on the first and last stitch or place a regular hdc in the last stitch to maintain count.
• Difficulty on small needles or bulky yarn: practice on mid-weight yarn first to learn the motion.

Variations & creative uses

• BPhdc in the round: work around the post of stitches in previous rounds for tubular ribs on hats and sleeves.
• Combine with front-post hdc** to create cables and basketweave textures.
• Use with double-height post stitches** (back-post dc) when you want taller, more dramatic ribs.
• Stripe + BPhdc: change colors on the BPhdc row to make textured color stripes.

Troubleshooting quick-fix checklist

• If stitches look flat → are you working into the post or top loops?
• If edges shrink → check turning chain technique and consider placing a turning stitch.
• If ribs are inconsistent → practice the hook angle; approach the post horizontally and wrap fully.

Q: Is BPhdc the same as back post htr (UK)?

A: Yes — US hdc = UK htr. So BPhdc in US terms is the same technique as back post half treble in UK terms.

Q: How do I count BPhdc stitches?

A: Count the posts you work around each post counts as one stitch. Use stitch markers to avoid miscounts at the edge.

Q: Can I substitute BPhdc for other post stitches?

A: You can substitute depending on texture and height needs. BPhdc is shorter than back-post dc, so choose based on the look and drape you want.
