Pattern Notes

  • The project is worked in rows.
  • The foundation multiple is 6 + 5.
  • Always carry the unused yarn up the side neatly.
  • The turning chains do not count as stitches.
  • The foundation starts with a chain to set up the base for the blocks.

Crochet Instructions

Foundation Chain

For a medium throw, chain 101 with yarn A (eucalyptus green).

Row 1

  1. Work a double crochet (dc) in the 4th chain from the hook.
  2. In the next chain, work another dc.
  3. *Chain 3, skip the next 3 chains, then dc in the next 3 chains; repeat from * across the row until the end, ensuring the row concludes with a 3-dc block.
  4. Attach yarn B (warm sand) without cutting yarn A, your project should now have a charming mix of green and sand shades.

Row 2 with B

  1. Chain 3 and turn your work.
  2. Skip over the first A 3-dc block. Working into the exposed foundation chains beneath the first ch-3 space, make 3 dc into those foundation chains.
  3. *Chain 3, skip the next A block and make 3 dc into the next exposed foundation-chain group; repeat from * across.
  4. Once you reach the end, turn your work.

Row 3

  1. Pick up yarn A.
  2. Work 3 dc into each A ch-3 space while creating ch-3 bridges over the B blocks.
  3. This row should enhance the interlocking appearance and maintain your color consistency.

Row 4

  1. With yarn B, work the same way into the B ch-3 spaces while bridging over the A blocks.
  2. When finished, turn your work.

Repeats

Repeat Rows 3-4 until the throw reaches your desired length. Remember to carry the unused yarn up the side neatly to avoid excessive tangling.

Finishing

  1. To complete the pattern, finish with one round of single crochet (sc) in yarn A around all four edges.
  2. Place 3 sc in each corner to enhance the finished look.
  3. Fasten off the yarn and weave in all ends meticulously.

Your throw is now complete, showcasing the beautiful interplay between the two colors and the unique interlocking stitch.

Tips for the Best Result

  • When working with multiple colors, be mindful of tension changes during color transitions to keep stitches even.
  • Use a stitch marker to mark the beginning of each new row to avoid miscounting.
  • This throw is a great opportunity to practice carrying yarn up the sides without cuts between color changes.

Common Mistakes

Uneven Blocks

Ensure you are using the correct count of skipped stitches and chain spaces to maintain uniformity across your blocks.

Color Blending Issues

If the colors seem to blend too much, consider adjusting the tension on your yarn; too tight can reduce the definition of each block.
