The pattern is Split Decision in the magazine McCall's Quick Quilts in the June/July 2012 issue. I actually really like the wavy lines idea, I found this and fell in love with it:

However, I don't have a wavy line setting on my machine! The closest thing I have is a zig zag stitch, which is close but not exactly what I want
I wish I had a more advanced machine!
