Decorating is a personal choice, what is OK for one may be horrible for another. That said.......I don't like the 1" square stuff in your pics, way too busy for me. Not as a stripe, and definitely not by itself.
I agree, but it is definitely your choice.I like the 2x2 glasss tile line at the top. Two of them, seems a bit "busy".
.....Not liking the lower line "with" the upper together: Too much going on.
