Open when you're feeling down. This envelop included a picture of Eeyore (because he is the epitome of sad) and a list of "16 Things to Do When You're Feeling Sad" and "25 Ways to Feel Better When You're Feeling Sad"
"Open when..." envelopes! These are perfect for military deployments or long distance relationships, etc. I grabbed 10 envelopes and put hand written letters in each of them, some with little treats. I also made an 11th envelope for just pictures!
