Use a marker to write your name on paper. Use either all capital letters or all lowercase and just focus on keeping the lines of the letters neat and even.
Choose one letter from your name and practice writing that letter out, each time adding different elements of style. Adding style to a letter could mean that it's bigger, more curvy, or has a bigger tail. Try this with a few different letters from your name until you find one that works the best.
Write your name out again using one of the stylized letters and use regular letters for the rest.
Switch the original cap on a can of spray paint for one with a thin nozzle, such as a "grey dot," "blue dot," or "gold dot super skinny."
Hold the paint can, nozzle facing toward your canvas surface, and squeeze down on the cap until a steady stream of paint is released.
Write out each letter in your name, including the one stylized letter. Release the button after creating each letter.
Keep practicing with both marker and spray paint until you've mastered both the tools and your new tag.
