Cluster stitch is a 2 row repeat perfect for blanket making.
Cluster Stitch: (CS): yo, insert hook, yo and pull up a loop, yo and pull through 2 loops on the hook three times, yo and pull through all 4 loops on the hook.
In my opinion this stitch looks better in a solid colour or an evenly variegated yarn.
Foundation Chain
Chain any even number.
