Soda Tab Flowers

I made these two soda tab flower pins this week using crochet thread, size 3 crochet hook, 6 soda tabs / pull tabs each, and a pin back each.  Here is the website where I learned how to make them, however it doesn't really give you a pattern to follow.  I did 5 sc on each tab with the inside color, joined to form a loop, and then dec in all the stitches between the soda tabs.  I dc around for the petals.
