thumb prints made into Christmas lights. Easy craft to do with the kids. To enhance this, I might extend the strand each year, so by the time they are older, you have a long string of thumb print lights.
Fun project to do with the kids! Melted bead suncatchers - *Layer cheap plastic beads in cake pans (no lining required), melt at 400 degrees for 20 minutes. Let cool & then flip them out. Drill a hole in it to make it a suncatcher.
