Chris/Richard,
Thank you for the input, that settles it. I will be going two deep.
Chris, I agree Pinterest can be helpful, unfortunately when I go looking something else usually catches my attention and half an hour later I haven't even begun to look into what I was initially interested in...
Richard, the in depth post that you had made is great and very helpful. If you wouldn't mind giving me the measurements that you used for the spacing that would be awesome.
Thanks guys.
Jesse
