I tried to figure out a new, different way to hang my students work this year. I used clothespins last year, but when the hallway got repainted over the summer- then my clothespins came down. I didn't want to fool with putting them up. So, I decided to just make something that would be easy to put up and take down. So, I got some yardsticks from Amazon....some purple clothespins from Oriental Trading...and some gorilla glue from Wal-Mart! I love these! I just attached them to the wall with some mounting tape which is also easy to remove.
