To make them, I used bulletin board borders for the part that goes around their head. I used foam sheets for the square on top, which I punched a hole through and stuck yarn through. I hot-glued the yarn onto the other side. Then I used two circle stickers that had cute graduation caps on them (from Dollar Tree) and put them back to back on the yarn. I hot-glued the head band to the foam square. Then to finish it off, I had them choose a color of puffy paint and I wrote their names. For another pre-k class at my school, I made them in white. They came out cute in both colors. :)
Here's our cute Graduation Handprint poems too! These poems are available in my TpT store and I've included poems for Preschool and Kindergarten! There's also certificates in the pack too!
When they come on stage, instead of handing out the real certificates, we hand out plain printer paper rolled up and tied with ribbon. Then we give the real certificates to the parents...no bent certificates that way! :)
