This is a great one day project. We always start each year with portraits (well...after the collaborative project)....so this is a great next project. It is a one day"er" too!! I start by giving each student a quarter sheet of paper to build upon. We talk about covering the paper, having a different color for the eyelid, making sure to grab white & black, and then three other colors that will make up the iris. We had discussed drawing an eye when doing our portraits, and I showed them how to transfer that eyedea (see what I did there ha ha corny dad jokes for days people!!) over to collage. Some struggled, but over all I thought these turned out pretty successful/fun!
