Not all handmade, off-registry gifts are bad. Most are very, very good! (I think of the registry as a tool of convenience, especially for people who don't know us well.) A good friend of mine is working on one right now. She is a very talented artist and calligrapher - back when I was in college I watched her gesso and gold leaf a ketubah, and didn't THAT make me wish I were Jewish. Her work is really amazing.
Anyway, she offered to calligraph addresses on all the invitations. So a few weeks ago I sent off the envelopes and guest list. When they come back they'll be ready to go, and much prettier than my chicken scratch. She also offered to match the ink to the green invitation print, and she'd have stuffed the envelopes too if I weren't such a lousy little control freak.
DJ and I didn't register for calligraphy, but isn't that a fantastic present?
