First, you'll want your beginning chain to be a multiple of 6, plus 3 for turning. I used worsted weight yarn for these pictures and for my afghan, but you could use any yarn and hook you wanted and just chain an amount according to how big you want your finished item.
Row 1: (2 dc, ch 2, 2 dc) in 6th ch from hook, *skip next 5 ch, (2dc, ch 2, 2 dc) in next ch; repeat from * across to within last 3 ch, skip next 2 ch, dc in last ch, turn.
This is what it should look like after the first row.
Row 2: ch1, sc in first dc, *ch 3, dc in next ch-1 space, ch 3, skip next 2 dc, sc between last skipped and next dc; repeat from * across, ending with last sc in top of turning ch, turn.
And this is what it looks like after the second row.
And this is after row 3.
That's it! Just keep repeating rows 2 and 3 for the pattern. Once you get in a rhythm with it, it goes really quickly. I've made scarves with this pattern, found here, and the baby blanket found here.
