layout dilema

I have the main blocks for my son's quilt and just can't figure out how I want it to look. I thought about putting sashing around the blocks, alternating a plain block with the pieced block or just running the blocks back to back. If I knew what I wanted to do I could move forward on it. I will have a nice long weekend to think about it. Of course it won't be here but I will think about it. I need to find somewhere in my house that gets good light that I can put up a design wall. So many questions so few answers.
