How to Crochet the Classic 3-DC Shell Stitch (Granny Stripe)

Whether you’re looking to texture a cozy blanket or build the perfect sturdy base for a trendy crochet handbag, the 3-Double Crochet Shell stitch is a timeless technique you need in your repertoire.

Also known as the Granny Stripe, this stitch works up incredibly fast and creates a beautiful, rhythmic texture. It relies entirely on working clusters of double crochets into the same space, making it a relaxing, beginner-friendly pattern once you get the foundation established!

Materials Needed:

  • Yarn of your choice (Medium worsted weight or a sturdy cotton works beautifully for bags)
  • Crochet hook matching your yarn size
  • Scissors
  • Tapestry needle for weaving in ends

Abbreviations (US Terms):

  • Ch: Chain
  • Dc: Double Crochet
  • Sk: Skip
  • St(s): Stitch(es)
  • Sp: Space

Pattern Notes:

  • Starting Chain Multiple: Chain a multiple of 3 + 1. (For example, 30 + 1 = 31 chains).
  • The turning chain 3 at the beginning of a row counts as your first Double Crochet.

The Pattern

Foundation Chain: Chain your desired length using the multiple of 3 + 1.

Row 1: Work 2 Dc into the 4th Ch from your hook. (The skipped 3 chains count as your first Dc, completing your first 3-Dc cluster). Sk 2 Ch, work 3 Dc into the next Ch. Repeat from * to * all the way to the end of the row. Turn.

Row 2: Ch 3 (counts as your first Dc). Skip the first 3-Dc cluster from the previous row. Work 3 Dc directly into the space between the clusters of the previous row. Repeat from * to * across the row. To finish the row, work 1 Dc into the top of the turning chain from the previous row. Turn.

Row 3: Ch 3 (counts as first Dc). Work 2 Dc into that very first space (right between the edge Dc and the first cluster of the previous row). Work 3 Dc into the next space between clusters. Repeat from * to * across the row. To finish the row, work 3 Dc into the final space between the last cluster and the turning chain. Turn.

To continue your project: Simply repeat Row 2 and Row 3 until your piece reaches your desired height!

Pro-Tip for Color Changes

If you want to create striking stripes, change your yarn color at the end of Row 2 or Row 3 during the final pull-through of the last Double Crochet. This stitch looks stunning when you alternate colors every two rows!
