My kids love to paint, so I had them make one big piece of art on the easel and then I cut it into shapes. They wrote thank-you notes on the back of the painted pieces.Tricia Hornback Decatur, GA
We write a list of synonyms to use in our thank-you notes -- marvelous, fantastic, awesome, fabulous -- and the kids try to use a different one in each note. By the last letter, they have to get pretty creative! Lorraine Lodge Timonium, MD
My kids love writing thank-you notes using invisible ink. We make the ink by whisking a tablespoon of baking soda with a tablespoon of water, then we dip a paintbrush or cotton swab into the ink and write the message on white paper. When it dries, it turns invisible. We also include a decoder card for the recipient with instructions on how to reveal the message. One way is to place a towel underneath the note and iron it on low until the message mysteriously appears. Melissa Richer Sheffield, Ontario, Canada
When guests arrived at my kids' birthday parties, we would ask them to write their address on an envelope. I would put the envelopes in a basket and draw a name during the party, and the winner would receive a prize. Then when it came time to write the thank-you notes, the hard part was done.

I always take lots of pictures at birthdays or holidays. The kids pick their favorite shot, and we use it to create photo cards. Sometimes we'll print a message on the cards, and sometimes I'll have the kids handwrite a special note.Allison Tate Delran, NJ
After my kids got a little older and had dutifully written thank-you notes for several years, we decided to get creative. We filmed short videos of the kids using, wearing, or playing with each of the gifts they received. Just as with written notes, they addressed the giver by name, showed the item, and said why the gift was appreciated. We then sent the videos to relatives via e-mail.Jennifer Steele Worthington, OH
"I purchased personalized return address stampers for each of my girls, which makes them feel very grown-up."Cherie Archibeque Lodi, CA
