Yarn around balloons Elmers glue! Could make these with a small opening in the top, and use as “vases” for the centerpieces, filled with a few fake flowers! Quick, inexpensive and easy! Could even do this as a craft with the mommies.
Yarn balloon spheres: Cut strands of yarn, blow up balloon. Mix equal parts craft glue & water. Dip yarn in glue, wrap around balloon. Hang balloon with clothesline & clothespin. Once dry pop balloon and remove. Modge-podge could work too.
