Spiral Flower Pillow Pattern - I'm a Crochet Ninja

A friend of mine called me a Crochet Ninja.  She has determined that there is nothing I can't figure out by looking at a picture and testing what I think works.  There's this pillow pattern on the Herrschners website.  It is called the Vintage Rose Pillow pattern.  It is beautiful.  This is the link, but it may or may not work.  Herrschners has done something with its website that messes with urls. Anyway, I am fascinated by this pillow pattern.  Rather than be individual rows of petals like my other pillow pattern, the design is a spiral and the petals spiral out from the center.  It is actually quite beautiful.  However, I'm not really interested in paying $19.99 for the kit,  even if it does come with the yarn.

So, I started testing. First, I crocheted a circle in spiral form.

Row 1: Magic Circle with Chain 2 and 12 DCs. Do NOT join.
Row 2: Starting in the top of the first DC from Row 1, in back loops only 2 DC in each stitch around. (24 DCs)
Row 3: In the back loops only, 2 DC, 1 DC, repeat around. (36 DCs)
Row 4: In the back loops only, 2 DC, 1 DC, 1 DC, repeat around (48 DCs)
Row 5: In the back loops only, 2 DC, 1 DC, 1 DC, 1 DC, repeat around (60 DCs)
Row 6: In the back loops only, 2 DC, 1 DC, 1 DC, 1 DC, 1 DC repeat around (72 DCs)
To finish my test, I did 2 DC in the next stitch, 1 HDC in the next stitch, 1 sc in the next stitch, a slip stitch in the next.  Fasten off and weave in ends.

Then, starting with the loops at the center of the circle, I made 2 HDC in one stitch, 3 DC in the next and repeated around the spiral for 2 rounds. Then I switched to 2 DC in one stitch, 3 DC in the next for the remainder of the spiral. The key to this pattern is that the petals are not too wavy, so 3 DC in every stitch is too many and makes the petals too wavy.  2DC then 3 DC seems to be the perfect combination.

I'll post pictures when I get some more yarn. I ran out of the color I was using.  :(
