There’s a variety of writing utensils available for calligraphy. One is the fountain pen, in which the ink is sucked up through the nib into a reservoir. This style of pen is ideal as a self-contained, sturdy and portable drawing tool. Fountain pens often have interchangeable nibs to vary line thickness. Dip pens consist of a plastic or wood holder also with a variety of nibs and can be used with watercolor, gouache and acrylics.
