I really love the look of mismatched frames on the wall and thought it would be a great collage idea for our living room, which still had a lot of empty wall space a year after moving in. Frames can get expensive but that's where the mismatched frames come in handy - I picked up most of these from Ross or Marshalls on sale! No need to matchy match when you're going for this type of look.
Here's my gallery wall. Not quite a full wall but you get the point.
The pictures are all from our travels or from our wedding. I like that they all have a personal connection - a story in each frame.
Speaking of stories, funny story: Mark happened to look over my shoulder and burst out laughing as I was writing this post. I said what, one of my 100 list items was to create a gallery wall, so here it is! And he said the reason why he was laughing was because in his cursory glance of the photo, he thought oh, that's a nice living room, not even realizing that it was ours! Made me laugh.
