If you go to any arts/crafts store, they should have calligraphy sets. I got a set at Wal-Mart a long time ago. I don't use it much because, well...I don't really enjoy calligraphy. Haha. I don't have the loose ink and specialized pens though. I have what is similar to a marker (for the lack of a better description) with a pointed tip on it. I have it in case I need it though.
I had to do calligraphy exercises in my art class every year (high school). It was busy work mainly. (We had pointless art classes that taught us very little.) We would do pages and pages of the crap. That is probably the reason I dislike it to this day, haha. I ended up sketching the letters out by hand and then filling them in with the loose ink. I'm sure my teacher noticed the difference but she didn't really care enough to say anything to me apparently. Haha.
The moral of that story is what, you may ask. Well, it is not to ask me for calligraphy advice. I'll tell you how to cheat on it. ;)
I would go with the label idea if you want less work and a professional look. Again, those are available at any store that carries office supplies...wal-mart included.
