It's a great start! Don't fret about matching just yet. I made one like this last year and honestly, I hated it right up until I finished binding it - then I fell in love. In the end when you have all that crazy color together, it works. If you need to impose order you can use a set color for either the center strip or the next one (one offset); then you'll have a pattern for the eye to "rest" on when it's done.
