Long ago, before computers became the generally accepted mode of communication, we used a pressed fiber sheet and graphite or ink implement with which to make markings on said sheet.
Many fibers can be used for making these sheets like cotton, linen, even elephant dung (ick) but my favorite, being cheap and readily accessible, is tree fibers. There are even forms that are pre-folded and contain art work and sometimes sentiments that may be appropriate for your occasion; like "Merry Christmas;" "Happy Birthday;" or "Thank you!"
Other accessories you may need are specially folded fiber sheets in order to send your message through the postal system* and the necessary postal tax.
*Postal system: an archaic system of boxes and sorting facilities run by government workers which collect and distribute articles and tax the users.
The implement you choose for marking with will need some practice to use well. Wrapping your fingers around close to the tip area will help. After many year of only scrolling your signature and occasional list, you may find that your hand cramps quickly; I suggest starting out slowly, and taking breaks as needed.
Though antiquated with the arrival of email and social networking, many are still moved my a single note sent by post. The art of writing a "thank you card," for example, though extinct prior to the internet communication takeover, still moves many to endearment of the sender and in turn causes the "thanked" to give thanks to the sender!
