This is a neat way of creating a wickedly sharp zig-zag and without the annoyance of complicated decreases. I've passed on this knowledge from a great book by Jan Eaton called Ripple Stitch Patterns (Quarto Publishing).
Multiple of 16 plus 2
Row 1: 2 dc into 2nd ch from hook, *1 dc into each of next 7 chs, sk next ch, 1 dc into each of next 7 chs, 3 dc into next ch; rep from * to end, ending last rep with 2 dc into last ch; turn.
Row 2: Ch 1, 2 dc into first dc, *1 dc into each of next 7 dc, sk next 2 dc, 1 dc into each of next 7 dc, 3 dc into next dc; rep from * to end, ending last rep with 2 dc into last dc, turn.
Rep Row 2 from now on.
I haven't mentioned colour changes as that is up to you. The stitch pattern is so easy to remember and to follow.
I'm planning a shift dress in the tradition of 60's Mary Quant with a hint of Missoni.
