I am hand-addressing wedding invitations and would like to use a calligraphy pen to do that. I tried out some ink pens today and found they were too wide. A friend suggested calligraphy fountain pens instead. I don't know anything about them and would like more information.

Keeping in mind that I'm a total beginner with calligraphy, here are some of my questions:
- Which one should I try? (specific brand and model)
- How is a calligraphy fountain pen similar or different from a regular fountain pen? Can I just use a fountain pen that I already own?
- Good online resources for buying calligraphy fountain pens?
- Other good calligraphy resources for beginners?

Try visiting a good Stationery store in your area. Most carry a good line of materials. You may not want to invest too heavily ($$$) if you are only doing a single project.

Since you already own a fountain pen, you may only need to buy a new nib (if yours is replaceable).

The only difference between a standard fountain pen and one used for calligraphy is the nib. A standard writing pen has a very fine point, where calligraphy requires a wider tip. Think of the difference between a ball-point and a highlighter.

I have used everything from the old quill pen & ink to reservoir fountain pens with various nibs to disposable calligraphy pens with equal success.

For modern papers, I actually prefer the less expensive ones. The ink will bleed through most paper if you use the old "dip" inkwell, or even most fountain pens.

And remember, it's important that you always hold the nib in one position (don't let the pen roll in your hand) to get the gradient line widths that make calligraphy so beautiful!
