Cast on an even number of stitches and knit 4 rows.
First pattern row: with crochet hook pull a loop through first stitch,
wool over and pick up another loop in same stitch, slip stitch from pin,
wool over and pick up a loop in next stitch, wool over and through all 5
loops on hook, ch. 1, thus forming one cluster, slip stitch from pin, *
wool over and pick up a loop in next stitch, slip off pin, wool over and
pick up a loop in next stitch, wool over and through all 5 loops on
hook, ch. 1, slip stitch from pin and repeat from * all across.
Second pattern row: pick up a loop in the back thread of second and all
remaining stitches, retaining loops on hook (as in afghan stitch). The
loop on hook will count as first stitch.
Knit 2 rows. These four rows constitute one pattern.
