The Dune Drift C2c Granny Spike Lap Blanket: A Free Crochet Pattern for a Textured, Modern Throw

Anonymous July 30, 2026

Introducing the Dune Drift C2C Granny Spike Lap Blanket

Wrap yourself in the cozy, sculptural texture of the Dune Drift lap blanket, a stunning corner-to-corner project that combines classic granny squares with dramatic spike stitches. This free pattern creates a richly layered, modern throw perfect for adding a touch of handcrafted luxury to any room. The blanket is worked diagonally from corner to corner (C2C) using a modified granny spike stitch, resulting in a highly dimensional surface featuring a grid of classic granny square clusters interspersed with long, dramatic spike stitches that stretch diagonally across the fabric. The warm, earthy desert gradient palette—pale sandy beige, muted sage green, and soft terracotta clay—creates a modern, organic aesthetic that feels like a piece of abstract textile art.

Materials Needed

Yarn

  • Worsted weight (#4) yarn in three colors:
  • Color A (Sand Dune - a warm, pale beige): Approx. 600 yards
  • Color B (Sagebrush - a muted, dusty green): Approx. 400 yards
  • Color C (Clay - a soft terracotta): Approx. 400 yards

Hook

  • Size J/10 (6.0 mm) crochet hook

Gauge

  • 4 granny clusters (3 dc) and 4 rows = 4 inches in standard granny stitch. Gauge is not critical for this project, but consistency is key for a neat finish.

Other Supplies

  • Yarn needle for weaving in ends
  • Scissors
  • Stitch markers (optional, for keeping track of rows)

Step-by-Step Instructions

Notes Before You Begin

  • This blanket is worked diagonally from corner to corner (C2C) using a modified granny spike stitch.
  • Each 'tile' is a small granny square cluster.
  • The spike stitch is created by working a double crochet into the row below.
  • The pattern increases until the widest point, then decreases.
  • Work with the right side (RS) facing you for all rows.

Abbreviations

  • ch = chain
  • dc = double crochet
  • sp = space
  • st(s) = stitch(es)
  • sl st = slip stitch
  • sk = skip
  • RS = right side

Special Stitch

Spike Cluster (SC): Work a dc into the center of the granny cluster two rows below (the space between the 3 dc of that cluster). This creates a long, textured stitch.

Pattern Instructions

Row 1 (Increase - RS)

With Color A, ch 6. In the 4th ch from hook, work 3 dc (this is your first granny cluster). Ch 1, dc in the same ch as the last dc of the cluster. (This creates the corner.) Turn. (1 cluster)

Row 2 (Increase - RS)

Ch 6. In the 4th ch from hook, work 3 dc. Ch 1, dc in the same ch. (New cluster). Sl st into the ch-1 sp of the previous row's corner. Ch 3 (counts as first dc of next cluster). Work 3 dc in the same ch-1 sp. Ch 1, dc in the same sp. (2 clusters)

Row 3 (Increase - RS)

Ch 6. In the 4th ch from hook, work 3 dc. Ch 1, dc in the same ch. (New cluster). *Sl st into the next ch-1 sp of the previous row. Ch 3, work 3 dc in the same sp. Ch 1, dc in the same sp.* Repeat from * to * across. (3 clusters)

Rows 4-10 (Increase - RS)

Continue increasing as established, working one new cluster at the beginning of each row. On Row 5, begin introducing Color B. Work 2 rows of Color A, then 2 rows of Color B, then 2 rows of Color C, then 2 rows of Color A, etc., creating a subtle striping effect. You will have 10 clusters across at the end of Row 10.

Row 11 (Increase with Spike - RS)

With Color B, ch 6. In the 4th ch from hook, work 3 dc. Ch 1, dc in the same ch. (New cluster). *Sl st into the next ch-1 sp of the previous row. Ch 3, work 3 dc in the same sp. Ch 1, dc in the same sp.* Repeat from * to * for the next 8 clusters. For the 10th cluster (the last one): Sl st into the ch-1 sp. Ch 3, work a Spike Cluster (SC) into the center of the granny cluster two rows below (the one directly below this space). Ch 1, dc in the same sp. (11 clusters)

Row 12 (Increase with Spike - RS)

With Color C, ch 6. In the 4th ch from hook, work 3 dc. Ch 1, dc in the same ch. (New cluster). *Sl st into the next ch-1 sp. Ch 3, work 3 dc in the same sp. Ch 1, dc in the same sp.* Repeat from * to * for the next 9 clusters. For the 11th cluster: Sl st into the ch-1 sp. Ch 3, work a Spike Cluster (SC) into the center of the granny cluster two rows below. Ch 1, dc in the same sp. (12 clusters)

Rows 13-20 (Increase with Spike)

Continue increasing, working a Spike Cluster into the last cluster of each row. Alternate colors every 2 rows. You will have 20 clusters across at the end of Row 20.

Rows 21-40 (Even - No Increase)

Work even without increasing. At the beginning of each row, do NOT ch 6. Instead, sl st into the first ch-1 sp of the previous row. Ch 3, work 3 dc in the same sp. Ch 1, dc in the same sp. Then continue across, working a Spike Cluster into the last cluster of each row. Continue alternating colors every 2 rows.

Rows 41-60 (Decrease with Spike)

Begin decreasing. At the beginning of each row, sl st across the first cluster (sl st into the ch-1 sp, then sl st into the top of the next 3 dc, then sl st into the next ch-1 sp). Ch 3, work 3 dc in the same sp. Ch 1, dc in the same sp. Continue across, working a Spike Cluster into the last cluster of each row. You will have one less cluster per row. Continue until you have 2 clusters remaining.

Final Row (Decrease)

Sl st across the first cluster. Ch 3, work 3 dc in the last ch-1 sp. Ch 1, dc in the same sp. Fasten off.

Finishing

Weave in all ends using a yarn needle. Block gently to shape, if desired, by lightly steaming or wet-blocking to even out the stitches and enhance the texture.
