I like the first 2 colors, but why not use two or even all three colors? I love to piece the backs of my quilts, it adds interest no matter which side is viewed, and some of them end up truly two-sided! Here are three simple ones...they're really not wonky, I'm still trying to train my DH on how to hold them (HA!! Wish me lots o' luck!!)
