These two pockets came home with my kids at the end of the school year (June 2015). The teachers took two poster boards and taped them together to create a big portfolio to hold artwork throughout the year. I will use these same pockets to collect artwork this whole school year 2015-2016. When it's time to send the grandparents their art books in September 2016, I will take apart these two pockets, which equals 4 poster boards in total and use 3 out of the 4 poster boards. Fold each in half and use them as envelopes for the art books. One poster board remains for next year. Recycling at it's finest.
