Reddit mentions of Staedtler Caligraphy Duo Markers, 3002C5

As someone who just started with calligraphy, I'm here to tell you, reddit: you can learn to write like this. Calligraphy is a great skill to learn in your spare time. It's not hard, just takes practice. This particular script is called Uncial (pronounced un-shel). You need a flat-tipped pen or marker. You can use a chisel tip marker if you have nothing else. If you feel like buying something to practice with, these markers are great for beginners.

You're going to write differently than you were probably taught. Write with your arm, not your fingertips. It takes some practice but you will be rewarded with some fine, fluid writing which may even surprise yourself. Here's more info.

Find a writing sample or maybe a guide from a book with letters that look attractive to you, and then try to recreate each one. (There can be many different variations on one script!)

Think back to first grade when you would write out a whole page of "a"s just for practice. That's what you're going to do. Whole lines of each letter. Practice until you start to understand the basic forms that make up the alphabet you're going for. For example, with uncial letters, the same c-shape stroke can become the letter C, D, E, G, O, Q, T, or U depending on how you finish it. Once you understand the basic shapes of a script, it will start to make sense and flow naturally through each letter. Just practice; write a little each day. You can do it!
