I am working on a OBW right now. I have it up on my design wall and am working on my arrangement. I have my 3rd attempt up now and am pretty sure I like it. I stare at it and move a few blocks every time I got in there. My machine is in the shop right now so I am using my old machine that I don;t like. I am working on some donation doll quilts until I get my good machine back.
There is a mirror that you can get for auditioning fabrics. I took a class years ago. 2 of us used the same fabric by accident. It was really interesting because they looked totally different when finished because we started in different places in the fabric. They hung side by side in the LQS for a while. You would never have known they were from the same fabric.
