Here's the progression of my fireflies...
I also offered a craft with this theme. I cut out a jar shape from black construction paper. I put out pans of glue with glitter stirred in it and the kiddos stamped with little porcupine rings to make fireflies in their jar. Easy Peasy! We recently got in this new firefly book. It's beautiful!! I want to use it next time I do this firefly theme! Fireflies are so much Fun with Friends at Storytime. There are more great ideas on the Flannel Friday Roundup. Check out the wonderful resources on the Flannel Friday Pinterest Boards. Here's the link for the official Flannel Friday blog for more info!
