Rocking Chair Custom Cushions

Right now I am leaning towards navy blue for the cushions on my rocking chair. There are tons of lovely ladies on Etsy that make custom slip covers and I just have to pick a fabric. So, think navy blue. I might change my mind after hearing everyone's votes for the rug, but here is where I stand now. What's better: plain navy blue in whichever fabric I like, symmetric (slightly Americana) stars, or "Peter Pan" stars?
