I haven't actually cut into the blue piece yet. I made paper copies of the sewn piece. That way, I could cut up the paper copies and "play" with them instead of cutting up the sewn piece. Here are two pictures of my design wall. Right now, I'm playing the "what if" game. If you'd like to see more detail about the process, you can check it out on my blog here.
In this picture, I have pinned blue paper pieces to the orange sewn piece. I have pinned bias strips (in dark navy) over the paper pieces. I thought the piece at the bottom looks a bit heavy, sooo...
I made the change below.
I'm thinking of adding a blue piece to the upper right side (where it looks like there is an "empty" bias strip). What do YOU think?
