Many little things separate decent penmanship from great penmanship, and with a little practice, you can improve your handwriting. Here are some tips for developing a beautiful handwriting style:

Choose a style.
Writers who work by hand can choose from a variety of handwriting styles. Most tend to prefer cursive handwriting, where uppercase and lowercase letters flow together on a piece of paper. Writers with particularly good penmanship may even choose a career in hand lettering and typography design. Calligraphers, for instance, practice the ancient art form of calligraphy, where letterforms are treated with the same care and respect as painted images.

Choose the right pen.

Modern calligraphy tends to rely on fountain pens, which lend themselves well to cursive writing. Ballpoint pens are more economical with their ink, and while they’re great for doodles and jotted notes, they tend to be insufficient for beautiful lettering.
Practice consistently. If you’re looking to improve your own penmanship—and perhaps return to the level of good handwriting you may have possessed in elementary and middle school—you can practice writing on lined paper as a starting point. You can practice writing by using a handwriting book, although the simplest form of handwriting practice is to simply write a passage of prose, focusing on one sentence at a time.

Use the proper grip.

Take care not to hold your pen in a vise grip; such a technique does not suit any style of writing, not even doodling. Guide your pen with your index finger instead.

Take a formal class.

Beyond grade school, it may be hard to find a handwriting class, but you can certainly find a calligraphy class in most major cities. Graphic designers may also teach community classes, although these tend to be for digital skills such as layouts and typography design.
