Fat Quarter Shop is great when it comes to BOM programs and their mysteries are always nice. It's important to note that this is just for the blocks; the finishing kit is $87.50 plus shipping and the backing is $56.63 plus shipping.
That being said, I never buy the finishing kit or backing because I always want my quilt to be somewhat unique. It is a 12-month program.
Fat Quarter Shop always includes a lot of fabric in each of their BOMs; you don't have to worry about making mistakes and not having enough. I really like the fabrics used in this one so I might take the plunge.
