Designed by Debbie Bliss, this pattern first appeared in Knits Accessories. I usually include a link to the instructions, but this pattern is so easy, I can post it myself. Here it is:
Chevron Stripe Pattern
Row 1: (RS) K1, ssk, *k9, sl 2 sts individually pwise, k1, p2sso; rep from * to last 12 sts, k9, k2tog, k1.
Row 2: K1, *p1, k4, (k1, yo, k1) all in next st, k4; rep from * to last 2 sts, p1, k1.
Rep Rows 1 and 2 for pattern.
This chevron stitch pattern lends itself particularly well to stripes, from a skinny scarf to an afghan. Make a few striped ones, and clear out some of your stash!
