One of the best ways to learn calligraphy properly is to make sure that you're holding the pen correctly. Calligraphy pens are practically pens, but they're held a little differently than most pens we use in our daily lives. The rule of thumb is to hold the pen at a 45-degree angle to your paper and keep your grip loose. If your grip is too tight, you're going to get fatigued early, which will show in your calligraphy as well.
