Ok i have googled this and found step by step instructions on how to do it...
Row 1: Purl row
Row 2: K1, P1, K1 into 1 stitch, P3 together * Repeat till the end
Row 3: Purl row
Row 4: P3 together, K1, P1, K1 into 1 stitch * Repeat till the end.
Knit the stitch, but before dropping off the loop from the left needle bring your yarn forward and purl, and again before you drop the loop off bring the yarn back and knit the stitch and then drop it off the loop
Wish me luck :O)
