How to Knit Mitered Squares Together (No Sewing Required!)

To Knit mitered squares is incredibly satisfyingโ€”theyโ€™re simple, portable, and perfect for creating blankets, afghans, or decorative pillows. But sewing all those little squares together? Not as much fun.

Hereโ€™s great news: you donโ€™t have to sew them together! You can actually knit your mitered squares seamlessly as you go. Today, Iโ€™m going to show you exactly how to attach mitered squares together using a simple step-by-step “join-as-you-go” technique.

Ready to knit your next beautiful projectโ€”without sewing a single seam? Letโ€™s dive in!


What Are Mitered Squares?

Mitered squares are knit diagonally, decreasing in the center until you reach the final stitch. They form beautifully crisp corners, making them ideal for modular projects like blankets or throws.

Whatโ€™s even better? By attaching each square as you knit, youโ€™ll never need a tapestry needle for assembly again.

  • Cast on stitches using a loose cast-on method (like the backward loop). This makes it easier to pick up stitches later.

Pro tip: Avoid a tight long-tail cast-on for modular knittingโ€”it makes joining squares difficult.

Step 3: Attaching the Next Square

  • Instead of casting on separately, pick up stitches directly along the edge of the first square.
  • Cast on the additional stitches you need (using the backward loop method) and knit your next square.

Repeat this step to keep adding squares!

Step 4: Continue Attaching Squares

  • Attach squares in groups of four, or knit as many as youโ€™d like!
  • Important: Always pick up stitches along existing edges to avoid holes.
