The Pretty Pebbles crochet stitch creates a 3-dimentional motif. This crochet tutorial uses US stitch abbreviations.
Special stitches: Clusters (CL): (yo, insert hook as per instruction and draw up 1 loop) x 3, yo, insert hook, yo,and draw through all 7 loops at once.
The foundation chain must have a multiple of 4 + 2. In my example, I began my foundation chain with 18 chs.
Row 1. 1 sc in 2nd ch from hook, 1 sc in each ch to end, ch 1. Turn.
Row 2. Sc in 1st st, *CL in next st, sc in next st*, repeat between ** to end, ch 1. Turn.
Row 3. Sc in each sts to end, ch 1. Turn.
Row 4. Sc in next 2 sts, CL in next st, *sc in next st, CL in next st*, repeat between ** to end, end with sc in last 2 sc, ch 1. Turn.
Row 4. Sc in each st to end, ch 1. Turn.
Repeat the rows 4 and 5 until you have reached desired length.
