The first day of school is so busy. Instead of taking pictures on the first day of school, wait a few days and take them on the 3rd day of 3rd grade, then take another one on the 3rd to last day of 3rd grade.
Pictures can be posted for open house and then given as an end of the year gift.
Pick your favorite color or mix and match! Signs are easy to make. Just print, laminate, tape to a paint stirrer, and snap the pics!
