Go to www.SumoPaint.com and click the large blue button that says, "Open Sumo Paint and start fooling around." This will open Sumo Paint without requiring a download.
Use the left-hand sidebar to select various tools. Use the ink, brush or pencil tool to draw with various colors, textures and thicknesses. Use the shape tools (such as star, polygon and circle) to create different shapes. Use the custom shape tool below the star to draw your own shapes. Change the size, thickness and direction of the shape by rotating and moving the mouse while the left mouse button is held down.
Change colors using the color picker on the right-hand side. First choose a color from the bar on the right-hand side, then change the shade of that color by moving the open circle within the square.
Import an image already on your computer by selecting File, then "Import to Layer" then "From My Computer." For an image online, select "From URL." You can then use the picture in your art by painting over it, cropping it or adding new images to it.
Click "Register Now!" on the Sumo Paint homepage to save your image to your Sumo account. This will allow you to share your work on the Web and get feedback from other Sumo users.
