so you see you can chose to do a very difficult center if you like or you can do something simplier. its up to you! and you can use a panel which pretty much couldn't be easier if you wanted it to be! so play to your own ability. I know that round after round even a simple center can be very detailed and colorful. I said before scrappy might just work great. I am using scraps in the yellow quilt, mixing them with white and think I can come up with a pretty rainbow quilt for my grand child. The other one will require some fabric purchases to get the desired combinations. I will have to ponder which one to use here and which to use in another round robin I am in.
