This is my favorite pattern by Patricia Kristoffersen. It's only 22 rounds and not that complicated. Row 17 can be a real pain because it takes forever to make all the strands of the petals, but it's well worth it. You really do appreciate how creative crochet can be with a pattern like this.
"Valerie" is a pattern from the book "Exquisite Doilies" and can be purchased here. I highly recommend it. I bought the book for $4 and I've done this pattern twice. The other patterns are lovely as well.
