That would be lovely! You should look around the internet and see if anyone already has something like that for sale, I'd think you could find it against ocean or mountains or whatever.
You've got the idea! That's exactly what I have in mind!
Oh yes, if I could find it already made, that would be great! Especially if I could find one with a river or ocean, since water quality is his main interest.
I love the part that says "This is my Father's world. O let me ne'er forget that though the wrong seems oft so strong, God is the ruler yet." I think it's encouraging...
