Soooo easy to do, pretty inexpensive if you frame your pictures or art yourself. AND when you group pictures together, they have a big impact on your room. I started looking around my house and I have them in almost every room.
Here are a few examples...
My gallery wall at the top of my stairs...
(don't mind the crooked pictures)
I think this is one of my favorite places in my home.
I love the fun pictures of my boys. Which were taken by one of my best friends, TERRI, who is an amazing photographer.
I've also helped a couple friends decorate their homes and in both, we put a gallery wall. Here is a picture of my friend ANGELA'S. It is on a HUGE wall in her kitchen and looks amazing...this picture doesn't do it justice.
