I wish I could help, but I am not good at over the internet stuff. I think you need bigger things but you probably already knew that. I like this bloggers style, if you like it maybe she has a mantle example somewhere. Good luck!http://www.adelightfuldesign.com/
What about one of those giant letters? Like a big B for Breedlove leaning against the wall, sitting on the mantle? I don't like anything in this picture except for the letter, but this is what I mean by big letter: http://2.bp.blogspot.com/_-yWNMWcLo-Q/S5-m4Bts3ZI/AAAAAAAAFL4/KjV4lUMHFEw/s640/mantle+twice+rememberedOr maybe a pitcher/vase of flowers? and some pretty colored pitchers? http://theinspiredroom.net/wp-content/uploads/2011/03/spring-mantel-idea.jpgGood luck! let us know what you come up with!
