Because don't you have a birthday party every weekend? It seems like we do.
I spotted these printable tags on Pinterest (naturally) and have stockpiled them like the crazy craft horder I am. They are perfect for either a boy or a girl and you can use them with flat ribbon since all the gifts get stacked up and tossed into the car.
Print some yourself today - you will be glad when Abby's party is tomorrow and you are totally prepared.
