Note cards

Bright ideas:
(1) Grant a wish. Arrange a large vase of tree branches into a centerpiece. On a note card, write a heartfelt good wish on one side Tie the note card to a ribbon and hang it on your tree. Repeat for as many guests as you anticipate. As guests leave, grant them a wish from the tree. They may take it and perhaps hang it in their own home or pay it forward.
(2)Use a slightly larger than normal sized place card for your dinner guests. In addition to writing their name on the card, write a blurb about the difference each person makes in your life. Here's an example: Constance... Thanks for making me laugh even when I don't feel like I can. Or, Dad... Thanks for constantly reminding me of how pretty I am.
(3) Create your own thank you cards. Or buy them. Either way, stick them in your purse or wallet and hand them on the spot at times when you'd like to express appreciation to someone. It's such an unexpected gesture that the recipient will be delighted. You're going to feel pretty special too, once you realize the frequency with which people deserve your thanks. Happens all the time, but we often overlook it.
(4) Send a hand-written note. It's always a meaningful, personal touch. National Postcard week is May 4-10.
HOWEVER, for your casual parties, scrap the paper and use green etiquette:
