I have decided I personally like these things:
Same color frames, but they can be different sizes
Set boundaries. (not sticking out more on one area then the other).
Words and/or shelves mixed in
Hopefully I will have time either this weekend or next to make something happen. I have a few frames, and a shelf or two that would be perfect for this project, but there aren't enough of them so I need to go dig some up either on clearance or at a thrift store. Plus I need to come up with some sort of word or phrase to place with my wall art. I'm torn between a vinyl decal to put on the wall, wooden letters to hang or even one of those nifty shelf words/phrases. I'm going to draw up a design and hopefully get going on this project soon.
