On the card I put a poem on one side and my "Crazy Kool Summer" message on the other. I found the poem on Pinterest as well, and I just liked how positive and upbeat it was! I used curling ribbon to attach the card and Kool Aid packet to the straw.
I would say that these gifts were a pretty big hit! The kids seemed to like them and I think they were different than anything else they had received in the past. I'm defintely doing this one next year!
