hatching an idea

I have been meaning to make my friend Sabina a quilt for her wedding (which was this past Sept) but just couldn't for lack of inspiration.  Finally, over the weekend it hit me.  Like, I couldn't sleep.  I've been mulling it over for the past several days and finally put my ideas on the page.  Here's my first mock-up:

Totally doable.  I'm still trying to decide if I want to move the orange in the top-right block.  Thoughts?
