Create ASCII Art

ASCII uses numbers, letters and all the symbols on the keyboard to make pictures.

Steps

Find a text editor to use to make your ASCII art (example: Notepad).
Set the font to one with fixed width. In Notepad, the only font that you can use is fixed width. This means that you can use spaces; in fonts without fixed width, spaces will be smaller, which can mess up text formatting.
Think of an object to draw. Start with something easy, such as a flower.
Use characters that take up more space for darker parts of the picture.
Use characters that take up less space for lighter parts of the picture.
Use various slants and slashes to make lines. You will be forced to only use large angles.
Save it and show your friends and family, or publish it on a website.

Experiment to find a design you like.
Start small, and work your way up. Almost no one can create some elegant masterpiece on their first, second, or even twentieth try.
Find programs over the Internet to help you create your pictures.
You will not be able to make perfect circles, but you can make figures that somewhat resemble circles by making bigger and bigger horizontal lines, and then making them smaller again.

Because you cannot make anything smaller than your characters, the size of each character will determine how small your piece of art can be. Because of this, you will not be able to make small figures with ASCII art.
Do not be too hard on yourself. ASCII art is a hard thing to master, and it will take time.
