I’ve been using this pattern to make 2-inch × 2-inch garter stitch mitred squares from left-over sock yarn. Of course, you can easily use yarn of a different gauge, and needles of a different size, or cast on more or fewer stitches than I suggest (although it should be an even number). This pattern is based heavily on instructions for mitred squares from Julia Trice.
You will need:
- left-over sock yarn (fingering weight, 8 stitches/inch)
- US #1 (2.25 mm) needles, or needles required to get gauge
- stitch marker
Cast on 32 stitches.
Row 1 (RS): Knit 14, slip 1 stitch purlwise, k1, pass slipped stitch over, place marker, knit 2 together, knit 14. 30 stitches remain.
Row 2 (WS): Knit all stitches
Row 3: Knit to two stitches before marker, slip 1 stitch purlwise, k1, pass slipped stitch over, slip marker, knit 2 together, knit remaining stitches.
Repeat rows 2 and 3 until 2 stitches remain.
Final row: Slip 1, knit 1, pass slipped stitch over. Cut yarn and thread through remaining stitch, pulling tightly.
