Flowerdy edging

Another edged flannel for my sister's baby and I wanted to echo the impressionistic flowers on the blanket. Some were three petaled and some were four, so this is what I came up with!

Materials:
Size 10 crochet thread
Size 7 crochet hook 1.65 mm

Stitches:
3 cluster flower:  *Ch 3, (yo twice, yo and pull through two loops, yo and pull through two loops) twice in first ch, yo and pull through all three loops on hook, ch 3 and sl st in first ch.*  Rep between * twice more to result in three petals in a row.

4 cluster flower: *Ch 3, (yo twice, yo and pull through two loops, yo and pull through two loops) twice in first ch, yo and pull through all three loops on hook, ch 3 and sl st in first ch.* Rep between * three more times to result in four petals in a row.

Round 1: Sc around, sl st in first sc.

Round 2: *3 cluster flower then sl st to complete flower in same st, sc in next 8 sc, sl st in next sc and begin 4 cluster flower then sl st to complete flower in same sc, sc in next 8 sc* rep from * around.
