My thinking runs along the same as Quiltsfor 's thinking. Coming up with something completely new and never seen before is near impossible. I'm also sure that the manufacturer suggests what colors they want to promote in a given year and how many thousands of yards they will make from a design.
I coudn't come up with a completely new design, in a new color, or size print that hasn't been done before and doubt if anyone else reading this could either. Give them a break!
