Handwritten correspondence: can never be replaced with other modes. becoming "a lost art": take time to send someone you care about a thoughtful, special handwritten letter on lovely paper, it will be appreciated more than you can imagine.
Antique vellum books are getting quite popular in decorating circles. They are very beautiful but as an avid reader my biggest pet peeve is book shelves filled with "books by the yard" that look good but you know no one reads.
I wish one of these was MY library. In MY house. Someday, I will have this. And when I die, my house will be donated to whatever county I live in to use as a library, and a museum. Fill it with books and history!
