|Sample knit with Silky Merino Heavy Worsted on US 7 needles|
I recommend adding at least two extra stitches - one for each side - just to neaten things up a bit. A seed stitch or garter stitch border would also look nice.
Multiple of 2
Row 1: *K1 wrapping yarn twice around needle, k1
Row 2: *K1, slip 1 wyif, dropping extra loops
Row 3: *Slip 1, k1
Row 4: *K1, slip 1 wyif
Row 5: *K1, k1 wrapping yarn twice around needle
Row 6: *Slip 1 wyif, dropping extra loops, k1
Row 7: *K1, slip 1
Row 8: *Slip 1 wyif, k1
Repeat these 8 rows for pattern.
