The website Piecing the Past usually has a free BOW running. After it's finished, she sells the pattern. I did her Rest and Refreshing BOW (18 weeks) and it's a beauty! Now it's selling for $15 for all those patterns. Not bad at all. I did it in civil war fabrics, but you can use any line of fabrics you want, or go scrappy from your stash. Check out that site to see the pretty BOWs she has done, that are now for sale. If you get on her mailing list you'll get notice of the next free one before it starts. She also has beautiful reproduction fabric for sale, if you need any.
