chain 2, single crochet in the first hole 4 times then a slip stitch.

Round 4: Same as round 2.
Round 5, 1 single crochet stitch in everyhole using single.
Round 6, now matching the picture, decrease everyother stitch.
round 7: Do 5 single crochets in everyhole, then do singles in every stitch 2 times around
