Boxes arrived...operation mailboxes in progress!!!

The boxes I ordered finally arrived!!! Now I'm starting to work on my next project...classroom mailboxes. I already have the pocket chart organization station from Lakeshore but the pockets are really tight and it's hard for the kids to put papers inside. With the boxes all they have to do is slide the papers inside!! I'm going to either paint the boxes or use patterned tape to decorate them. Will post an updated photo once they are complete.

The boxes I ordered in the process of becoming mailboxes!!!

Now I must admit...I saw this idea on Pinterest and when I realized that I could get the boxes for FREE I rushed and logged onto the USPS website and placed my order. It wasn't until AFTER I had ordered my 2nd set (the first set didn't arrive within the amount of time specified on the site and I thought something had gone wrong with the order, so I placed a 2nd order) I read the fine print and it states that the boxes should be used for mail purposes only!!! So this same project could be done with cereal boxes.
