Zig Zag Lace

Had to post a pic of one of my current wips. A zig zag lace scarf in Rowans Calmer. The pattern is very easy and goes like this:

Rows 1,3,5 & 7: *p1, ssk, k2, yo, k1*. Repeat from * to * until end of row.
Rows 9, 11, 13 & 15: *p1, k1, yo, k2, k2tog*. Repeat from * to * until end of row.
Rows 2, 4, 6, 8, 10, 12, 14, 16: *k1, p5, k1*. Repeat from * to * until end of row.

Repeat this patern sequence until you reach desired length and cast off in pattern. As for casting on, you need to cast on in multiples of 7. The peach scarf I cast on 42 st on 4mm needles in Rowans Calmer. The purple scarf I can't remember how many I cast on or the needles I used but I'm going to frog it and redo it as it's too wide and I would prefer it skinnier and longer. The purple scarf is knitted in Touch yarns.
