Calligraphy is an art that just about anyone can do. All you need is a pen and paper, and you're ready to do calligraphy.

Indeed, it requires very few materials - you don't need very much space - and, since you can probably write anyway, you already know the basics. 

Calligraphy is an art form in which patience and attention to detail are more important than artistic talent. That means you don't have to be an "artist" to be good at calligraphy. 

There are a lot of ways that people can use their calligraphy:

Poems,

Invitations,

Greeting Cards,

Business Cards,

Announcements,

Maps,

Poster

And many other useful items.

You'll have the opportunity to use your calligraphy skills every time you write.
