This was ok.
It was free.
It's easily interchangeable.
We could hang multiple pieces at one time.
The artwork always seemed too cramped so you couldn't really appreciate one masterpiece at a time.
It was really high up at the top of the wall so you had to stretch to see the art.
The only string I had at the time was hot pink, which doesn't match any thing else in the office and seemed out of place.
All in all this just wasn't working for me anymore. One day while perusing the dollar tree I came accross some clipboards and thought these would be perfect to replace the string and clothes pins. So after a snip of the scissors and some nails in the wall. We have a new art wall.
