I'm bad, i don't know where to start for design your own, I just see a pattern or fabric i like, (never buy enough) and try to put it together in some sort of layout. I have only done 2 of my own, and a quilt as you go, that was a class one and the 2nd i used up the scraps. I will eventually get more involved into the planning and set out of it, i suppose. But working full time, i don't get the time to concentrate on the designing until i am ready :)
