I think most people do their best creative work when they are enjoying themselves. If scrappy is not your personal bliss, why not do whatever makes you happy? I'm assuming quilting is your hobby and not an obligation. While you're making your structured project, it wouldn't hurt to do a little experimenting - as long as it's fun! - such as switching a few pieces around on your design wall to just see what they might look like. Then it's not a commitment to do that, just an opportunity to try a different way of looking at things. Tell yourself it's a quilt and nobody's life will depend on how you decide to make it. On the other hand, here is a place (plenty of good places, actually) in this world of quilting for highly organized people. Embrace who you are and let your project express you.
