I've suggested many pieces from Gathered Nest Designs to my clients and I even have a piece of my own...
number art found here
My suggestion with art is consistent in that I like large art with matted frames so that the art makes an impact. All too many times I see gallery walls online that have great selections of art, but the size and scale is just too small. If you are going to do a gallery wall, then go big.
I wanted to share a few of the pieces I'm loving through Gathered Nest Designs.
I'd frame this one with a large white mat and a black frame to join the love print above along with the two below.
All would be so cute together in a boys room!
