All those suggestions are awesome!...YES, it makes a difference to have the outside AS WELL as the inside something inviting to the eyes. I am known at the post office for the "girl with cute packages" ...I am trying to recycle materials, and reuse bubble mailers and such, and embellish them with origami paper or kraft paper with unique stickers, and lately had a xerox copy of an old Hawaii map, which was PERFECT for the customer since I am shipping from Hawaii....makes mail more exciting!
I agree that a gift tag somehow attached to the teddy bear would be cute, even giving it a story or a name!...BEST WISHES!
