Decor Thoughts: Floral wall/background

I'm still on the lookout for interesting design ideas since I'm planning my brother' wedding (TBD date).  I came across these two images and was smitten.  I totally want to use them somehow but how?

Ruche's floral wall with flowers made out of butcher paper

I like this because:

• you can make it ahead of time
• they can be used afterwards
• different sizes can be created
• different colors can be created

The garland or runner idea could be kinda interesting too.

Then there's the real floral wall here

From here

Gorgeous.  Simply gorgeous.

But I can only think of using these backgrounds for the ceremony or a photo booth.  Would there be other uses for these floral backgrounds?  I am just a sucker for anything pretty...oh and if I made all those paper flowers, they'd find their way into a wall in my home.
