Along the left side of the paint program are some little action boxes. A dotted star, dotted box, bucket, spray can, A for text and a pencil. Next to the pencil is a paint brush. When you click on the paint brush, a box will appear below with brush tips. Round, diamond, square in asst sizes, and / lines. Click on the center / line. Now with your mouse draw the letter S. It will appear in black. Click on a color in the table at the bottom and then make another S. I did black, red, blue and orange, on top of each other for a really cool effect.
You can save your scribbles, but they are in BMP format. These are really large files. I open them with Paint Shop Pro and convert them to GIF format, then upload to the net.
