A while ago I came across the blog Giver's Log and their happy mail, where she talks about how you can mail all sorts of things 13 ounces or less. Well, we had friends come visit from out of town and they left a toy. When I saw a discarded mini water bottle, I thought I should shove it in there instead of using a boring envelope - so I did.
You've got to check out the Giver's Log - because wouldn't it be awesome to get a bouncy ball in the mail?? Or send some Easter treats - possibilities are endless! There are tons more ideas listed.
