Before you start

Four-step harlequin stitch crochet instruction grid

Harlequin stitch depends on grouped stitches that open like small shells or flower bursts. Work a small swatch first and focus on keeping every cluster the same height.

Foundation row

  1. Chain a multiple that gives you enough room for repeated cluster groups.
  2. Work a simple setup row of single crochet or double crochet so the first decorative row has a stable base.
  3. Turn your work and keep your tension relaxed.

Make the first cluster group

  1. Chain to bring the row up to height.
  2. Work several double crochets into the same stitch or space to create the first raised shell cluster.
  3. Skip the next stitches as needed so the cluster can open without crowding.
  4. Anchor the group with a small stitch before beginning the next cluster.

Build the diamond effect

  1. On the next decorative row, place the new cluster between the clusters from the row below.
  2. This offset placement creates the staggered diamond look.
  3. Change color at the row edge if you want the harlequin pattern to stand out more clearly.

Repeat the pattern

Continue alternating cluster rows and placement so the flower-burst shapes stack into diamonds. Keep the skipped spaces even and check the front of the fabric often.

Finishing tips

  • Block the swatch lightly to open the cluster texture.
  • Weave in ends carefully along the back of the color-change rows.
  • Use the same hook size throughout so the diamonds stay even.
