That's me - I started with a custom chart that a friend gave me, but since then I've made a new one in Word that reflects the 3 main ribbon sites I order from. It's not hard at all, just takes some time to move the ribbon pieces to the new one.
I'm currently in the process of updating and would be happy to share the file when I"m done. It might at least inspire you or provide a starting place for your own. Then all you would need are all the little ribbons to put on it. That's why I started with a pre-made one. Much cheaper than finding a yard of every single ribbon color!
