Tutorial: How to Crochet a Half Hexagon

Whether you’d like to fill in the edging on a hexagon afghan or simply want to make multi-colored hexagons, this easy, free pattern will teach you how to crochet a half hexagon and customize the size to meet your needs.

Hexagons are my fave. That’s why I’ve used them in this popsicle stick hexagon shelf, this giant squishy knit object and most recently in my “Happy Hexagons” free afghan pattern.

For my afghan, I decided I liked the look of the geometric edge, but if you’d like a straight, even edge on your own blanket, half hexagons are where it’s at.

These half hexagons are made very similarly to my basic hexagon pattern, but the difference is that these are worked in back and forth rows and the full hexagons are worked in the round. I think hexagons and half hexis are the perfect portable crochet project to stash in your purse.

Hexagons are similar to crochet circles or squares in that once you understand the basic math of the increases, you can customize your hexagon to whatever size you wish by just adding more rounds (or in the case of a half hexagon, rows) and continuing to increase as you go.

If you're wondering how to get the edges of your hexagons straight and your edges just so, make a $2 blocking board and they'll all look nice and tidy.

How To Crochet a Half Hexagon

NOTE: Using worsted weight yarn and a size H hook, this pattern will create a half hexagon that has a 6” diameter, which is the perfect size to complement to my “Happy Hexagons” afghan pattern. For a larger or smaller half hexagon, just increase or decrease the number of rows. 

Row 1 (WS): Begin with a magic ring. Ch 1 to secure the magic loop and then ch 2 more (counts as first dc), dc in magic loop, [ch 2, 2 dc in magic loop] twice; turn. (Now you have 3 sides and 2 corners. The 2 dc will become the sides of your hex and the ch gaps will become the corners.)

Row 2 (RS): Ch 3, dc in first dc (inc made), dc in dc, (dc, ch 2, dc) in ch-2 corner, dc in next 2 dc, (dc, ch 2, dc) in ch-2 corner, dc in next dc, dc between last two stitches (inc made), 1 dc in tch; turn. (Each half hex side now has 4 dc.)

Row 3 (WS): Ch 3, dc in first dc (inc made), dc in next 3 dc, (dc, ch 2, dc) in ch-2 sp, dc in next 4 dc, (dc, ch 2, dc) in ch-2 corner, dc in next 3 dc, dc between last two stitches (inc made), 1 dc in tch; turn. (Each half hex side now has 6 dc.)

Row 4 (RS): Ch 3, dc in first dc (inc made), dc in each dc to corner, (dc, ch 2, dc) in ch-2 corner, dc each dc to next corner, (dc, ch 2, dc) in ch-2 corner, dc in each dc until tch remains, dc between last two stitches (inc made), dc in tch; turn. (Each half hex side now has 8 dc.)

Row 5 (WS): Rep Row 4. (Each hex side now has 10 dc.)

Row 6 and beyond: Rep Row 4. (Each side will increase by 2 sts per row.)
