McKenzie by Dena Designs fabric since it used black with pastels. I think that will be an interesting contrast.
I'm also trying to step out of my bubble and mix fabric lines. I was thinking about it and I think I tend to stick with one line per quilt because I don't really have a great LQS nearby. For those of you who freely mix fabric lines, do you have a local shop or are you buying online? How do you get over the fear of things not matching when you buy them online? Or is that just a good way to build stash? haha!
