Begin with ch6, then, beginning into the 2
nd stitch from the hook, work 5 sc down along the chain, then 1 sc into the stitch at the head located next to the first stitch.
Now, turn work, and continue as follows on the other side: 4 sc up the chain, then 3 sc into the same stitch, then 5 sc to the end, in the direction towards the begin of the petal, and join with 1 sl-st into the stitch at the head located next to the first stitch.
See more about this method in the video
here. Place petals 1 stitch apart from each other, i.e. when beginning the next petal, count off 2 sts from the end of the previous petal, and work the chain into the 3
rd stitch. You should have a total of 12 petals.
