Crochet Connected Spiral Pattern
Cluster4 (CL4) = work 3dc over stem of dc just worked but leaving last loop of each dc on hook, then work 4th dc as indicated leaving last loop as before (5 loops on hook), yo and through all 5 loops.
The quantity of sts is multiple 3 + 5.
1st row (RS): Work 1dc into 6th ch from hook, *3ch, skip 2ch, work cluster4 placing 4th dc into next ch; rep from * to last 2ch, 3ch, work cluster4 placing 4th dc in last ch, turn;
2nd row: 3ch (count as 1dc), 1dc into next 3ch sp, *3ch, work cluster4 placing 4th dc into next 3ch sp; rep from * to end, placing final dc into top of ch at beg of previous row, turn.
Repeat the 2nd row.
