Finished Dimensions:

Instructions:

Patchwork Squares:

Each square consists of a series of triangles. Create as many squares as you need to fill your blanket.

  1. With Yarn A, ch 30.
  2. Row 1: Sc in 2nd ch from hook, sc across (29 sc).
  3. Row 2: Ch 2, turn. Dc in each st across (29 dc).
  4. Row 3: Ch 1, turn. Sc in each st across (29 sc).
  5. Change to Yarn B. Repeat rows 2-3 for 5 more times. (You should have 6 total stripe rows.)
  6. Cut Yarn B, leaving a long tail. Change to Yarn C, and attach in the top left corner of the square.
  7. Create a triangle by working 5 dc into the first stitch of the row. Then continue adding rows of dc until the triangle shape is formed, ensuring to switch colors as desired.
  8. Repeat this process until you have 20 completed squares with different color combinations.

Assembling the Blanket:

  1. Lay the squares out in a 4x5 grid, alternating colors for a pleasing visual effect.
  2. Using slip stitch, join the squares together, starting from the first square in the top row and moving left to right.
  3. Once all squares are joined, create a border around the entire blanket. With your chosen border color, attach yarn with a sl st, ch 1, and sc evenly around the edges.
  4. Finish with a round of dc, making sure to create 3 dc in each corner for added stability.

Finishing:

Weave in all yarn ends with a tapestry needle. Block the blanket if desired to shape it better. Enjoy your cozy, colorful creation!
