Message eggs - weird message they have inside but I thought it would be cute for telling loved ones about baby news. Just remember to wait a few days for the leftover egg to dry that didn't come out before you put the note in.
This would be great hanging from shepherd's hooks at our front door. A couple of sets of white lites, basket fillers of greens, perhaps a wet foam block inside ? Outdoor shatter proof ornaments, pine cones wired in, and voila !
