|Sample knit with worsted weight yarn on US Size 8 needles|
Cast on a multiple of 4+4
Row 1: p2 *yo, p4tog; rep from *, end p2
Row 2: k2 *k1, (k1, p1, k1) into yo; rep from *, k2
Row 3: knit
Repeat these 3 rows for the pattern.
The edges are not neat, depending on how you plan to use the stitch you may want to add a border to neaten things up.
If you are beginning the pattern right from the cast on row, cast on loosely or work a row of plain knitting (loosely) so that the p4tog in Row 1 is easier to work. Work Row 3 loosely also to make Row 1 easier.
