I did not create the signs they came from a site called Remodelaholic They had the printable signs for free for the frist and last days of 2015-206 school year. I am sure there are other sites out there, but this is the one I found for this school year.
It had edges on the papers, so being crafty as I am, i cut each sign and matted them on cardstock. Here is a video tutorial on how I made the signs.
So if you school year is not over yet, here is a fun idea to get those cute end of year photos of the kids holding signs!!!
