Interrupted Rib Stitch Knitted Scarf

I knitted another scarf to donate. I found the interrupted rib 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 2 + 1 stitches (I cast on 23 stitches).

• Row 1 (RS): P1, *k1, p1; rep from * to end
