Working on the Gallery Wall

I have been searching around looking for idea's and tips on how to hang a gallery wall. I painted down the hallway and the stairs yesterday so all that is on the To-Do list is to hang all of my pictures 

I found a few pictures for inspiration

I am in love with the color of these frames! The white with the pops of turquoise and blue, so cute!

This is what I am working with

Wish me luck I am going to be hanging all of my pictures tonight!
