Bubble letters can be fun and expressive. They can be drawn to represent your own funky style. This is also a great way to learn typography and enhancing the look of posters, brochures and all kinds of artwork. You can try out between thick and thin bubble letters. Draw a letter with a single line and then draw an outline around the letter so that there are no sharp corners and angles. Keep drawing till your bubble letter is as big as required. Erase the interior outlines so that there are no marks. Color the letter the way you want to and your bubble letter are formed.
