The Peonie Duffle Bag is based on the pattern designed by C L Halvorson. I did make a fairly major change, instead of using the Daisy square pattern, I went with the Peonie pattern, which I found in 200 Crochet Blocks by Jan Eaton. I find Jan Eatons instructions to be really clear and very pretty, this is my go to book when I am making throws and afghans.
