Idea for Hallway

I am looking for a cute and inexpensive way to hang student work in the hallway at school. I have one set of sentence strips that can be used, but its not enough room. I looked at ordering more sentence strips but in order to have enough room I'd have to spend another $50-$60.

Here are few ideas that I found and am interested in.....give me your opinion!
Option #1 - Use thin boards and clips to display student work.


Option #2 - Student Work Tree
I love the look of this tree and would LOVE to add a few glittery clothes pins in the mix to hold student work but I'm not sure.   


Option #3 - Yard sticks and clothes pins...

I would love your opinion on this matter..... come on...give it!! :0)
