Diagonal Scallop Stitch Knitted Scarf

I knitted another scarf to donate. I found the diagonal scallop stitch pattern on New Stitch a Day's website. 

I used a Caron Anniversary Cake Special Edition (the colour is Holly Jolly) and 6.5mm needles. 

Cast on multiples of 4 stitches plus 2 (I cast on 22 stitches). 

• Row 1 (WS): Purl 
• Row 2: K1, *insert needle from behind under the running thread between the st just worked and the next st, thus putting an extra strand on the needle; k2, then pass the extra strand over the 2 knit sts; k2; rep from *, end k1. 
• Row 3: Purl 
• Row 4: K3, *insert needle from behind under the running thread between the st just worked and the next st, thus putting an extra strand on the needle; k2, then pass the extra strand over the 2 knit sts; k2; rep from *, end k1.
• Repeat rows 1 to 4, knitting to the desired length
• Bind off
