Decorating the walls

I'm not interior decorator, as you've seen from the photos.  But that doesn't mean I can't try!

We have lots of empty wall space in our house and in an attempt to alleviate that, I've been looking for inspiration to move some of the photos on our mantel piece to our wall and then a few more to show off.

I used this site for inspiration:

I went to Jo Ann's for fabric for a baby quilt (that's a whole other post!), and all frames were 40% off.  so I bought a bunch.  I also bought matting to go around the photos.  I bought too many, I'll have to take a few back, but I didn't want to have to go back.

First, I wanted to test out the layout, so I cut and pasted a bunch of paper together in the correct sizes (pretty close) and then put those on the wall to get an idea for what kind of layout I wanted.

This is one of the layouts I tried.

I measured out the distances, stuck some nails in the walls, and voila - photos below!

Though, now I wonder if it looks okay?  My husband looked at it and said 'you didn't center the photos'?  I didn't center them because above where the plant is, we've talked about hanging lights (maybe one like the Hobbs Sconce on one kings lane) either a wall sconce or a hanging lantern / light to add more light over tehre.  Over maybe a plant a bit more compact, like a miniature ever green or something.

And yes, the middle picture is missing.  I'm waiting on it to get delivered.

I don't know, should I move them closer together or center it on the wall?
