For those on your list year that you just don't know what to get this might be something that would make a perfect gift. Stationary is a great way to give something that's personalized. You can buy blank cards with envelopes at Michaels. Get a stamp that reminds you of them and stamp the image on the card. This is the set I made.
You can get a stamp with the person's initial, their favorite animal or just something that represents their personality. Use different colors of note cards to make them more unique. I know that I love stationary and it's a great way to keep in touch with those far away.
