Celestial Drift C2C Pixel Graph Throw Free Pattern – Crochet a Starry Night Sky Blanket

Celestial Drift C2C Pixel Graph Throw Free Pattern – Crochet a Starry Night Sky Blanket

Imagine wrapping yourself in a piece of the night sky—a swirling galaxy of deep blues, soft whites, and golden stars, all crafted with your own hands. The Celestial Drift C2C Pixel Graph Throw is a corner-to-corner crochet project that transforms a pixel graph of a starry night into a cozy, textured masterpiece. Each tile is a single C2C block, making this a meditative, beginner-friendly project that builds row by row into a stunning 40x40 inch throw. Whether you're new to C2C or a seasoned crocheter looking for a relaxing project, this pattern offers a rewarding journey with a celestial payoff.

Materials Needed

Before you begin, gather your supplies. This pattern uses worsted weight yarn in five celestial shades, a standard crochet hook, and a few basic tools.

• Yarn: Worsted weight yarn in 5 colors:
  • Midnight Blue (MC) – approximately 1800 yards
  • Soft White (CC1) – approximately 400 yards
  • Golden Yellow (CC2) – approximately 250 yards
  • Dusty Lavender (CC3) – approximately 200 yards
  • Pale Teal (CC4) – approximately 150 yards
• Hook: 5.5 mm (I-9) crochet hook
• Gauge: 4 C2C blocks = 4 inches (10 cm) in C2C pattern
• Other: Yarn needle for weaving in ends, scissors

Understanding the C2C Technique

This pattern uses the corner-to-corner (C2C) technique, working diagonal rows of blocks. Each block is a ch-3, 3 dc cluster. You will follow a pixel graph to determine color changes. The graph is 40 blocks wide by 40 blocks tall, resulting in a 40x40 inch throw.

Abbreviations

• ch = chain
• dc = double crochet
• sl st = slip stitch
• MC = Midnight Blue
• CC1 = Soft White
• CC2 = Golden Yellow
• CC3 = Dusty Lavender
• CC4 = Pale Teal

Graph Reading

The graph is read from the bottom right corner, moving diagonally. Each square on the graph represents one C2C block. The first row is 1 block, the second row is 2 blocks, and so on until you reach the widest point (40 blocks), then you decrease. When reading the graph, each row is read from right to left, starting at the bottom.

Step-by-Step Instructions

Starting (Increase Phase)

You'll begin at the corner and work diagonal rows, increasing by one block each row until you reach 40 blocks across.

Row 1: With MC, ch 6, dc in 4th ch from hook, dc in next 2 ch (1 block). Turn.

Row 2: Ch 6, dc in 4th ch from hook, dc in next 2 ch (block 2), then sl st into the ch-3 space of the previous row's block, ch 3, 3 dc in same space (block 1). Turn. (2 blocks)

Row 3: Ch 6, dc in 4th ch from hook, dc in next 2 ch (new block), sl st into ch-3 space of next block, ch 3, 3 dc in same space, repeat for each block across. Turn. (3 blocks)

Continue increasing in this manner, adding one new block at the beginning of each row. When you reach a row where the graph indicates a color change, use the new color for that block. To change colors: work the last dc of the previous block with the new color, then continue with the new color for the next block. Carry the unused yarn loosely along the back or cut and weave in ends.

Following the Pixel Graph

Follow the graph row by row, increasing until you have 40 blocks in a row. The graph for the starry night design is as follows (each row is read from right to left, starting at the bottom):

• Rows 1-5: All MC.
• Row 6: 1 CC1, 4 MC.
• Row 7: 2 CC1, 5 MC.
• Row 8: 1 CC1, 1 CC2, 1 CC1, 6 MC.
• Row 9: 2 CC1, 1 CC2, 2 CC1, 7 MC.
• Row 10: 1 CC1, 2 CC2, 1 CC1, 8 MC.
• Row 11: 2 CC1, 1 CC2, 2 CC1, 9 MC.
• Row 12: 1 CC1, 1 CC2, 1 CC1, 10 MC.
• Row 13: 2 CC1, 11 MC.
• Row 14: 1 CC1, 12 MC.
• Row 15: All MC.
• Rows 16-20: All MC.
• Row 21: 1 CC3, 19 MC.
• Row 22: 2 CC3, 20 MC.
• Row 23: 1 CC3, 1 CC4, 1 CC3, 21 MC.
• Row 24: 2 CC3, 1 CC4, 2 CC3, 22 MC.
• Row 25: 1 CC3, 2 CC4, 1 CC3, 23 MC.
• Row 26: 2 CC3, 1 CC4, 2 CC3, 24 MC.
• Row 27: 1 CC3, 1 CC4, 1 CC3, 25 MC.
• Row 28: 2 CC3, 26 MC.
• Row 29: 1 CC3, 27 MC.
• Row 30: All MC.
• Rows 31-40: All MC.

Pro tip: As you work through the increase phase, count your blocks at the end of each row to ensure accuracy. The graph rows are short at first, but they grow quickly—stay attentive to color changes to keep the galaxy pattern crisp.

Decrease Phase

Once you have 40 blocks in a row, begin decreasing. This shapes the opposite corner of your square blanket.

At the start of each row, sl st across the first block to the next ch-3 space, then ch 3, 3 dc in that space, and continue across the row. Do not add a new block at the beginning. At the end of the row, do not work the last block; instead, turn and begin the next row with a sl st. Continue decreasing until you have 1 block left. Fasten off.

Detailed Decrease Example:
Row 41 (first decrease row): Sl st into the ch-3 space of the first block, ch 3, 3 dc in that same space (this counts as your first block of the row). Work 3 dc in each ch-3 space across the row, but stop before the last block—do not work into it. Turn. You now have 39 blocks in this row.

Repeat this process for each subsequent row, always skipping the last block and slip stitching over the first block. The row count will decrease by one each time until you reach a single block.

Border

With MC, work a border of single crochet (sc) around the entire blanket, working 1 sc in each block edge and 3 sc in each corner. For a decorative touch, work a second round of sc in CC1 (Soft White). This clean border frames the celestial design beautifully.

Finishing Touches

Weave in all ends using your yarn needle. Block the blanket to even out the stitches and enhance the pixel design. To block, gently wet the blanket, lay it flat on a towel, and pin it to the correct dimensions (40x40 inches). Allow it to dry completely before removing pins.

Your Celestial Masterpiece Awaits

The Celestial Drift C2C Throw is more than just a blanket—it's a journey through the stars, one block at a time. The repetitive rhythm of C2C makes it a perfect project for relaxing evenings, while the stunning galaxy pattern keeps you motivated to see the next color emerge. Whether you gift it to a stargazer or keep it for your own cozy nights, this throw is sure to become a treasured heirloom.

Happy crocheting, and may your nights be filled with celestial drift!
