Maybe I missed it, or maybe it doesn't say specifically which side you should seam the squares together on. So, I started seaming from the back. I pieced 8 squares together before I decided that I liked how the seam looked on the back much, much better than on the front.
So I'm starting over. It was a DUH moment. I usually do seam pieces on the front side. What was I thinking??
So, here's a tip for you.. seam on the front side.
