First Download the program and it is free!
For windows it is called 'paint.net'
For Mac it is called 'paintbrush.com'
Open the program by choosing with Paintbrush or Paint
choose your blank digi (Yours won't be watermarked)
Start coloring!
You can print out several digi's, in any size you want from as large as your paper is, to tinie tiny! And change the color and direction.
Just each time you print it, choose 'SAVE To' and then it will ask you where to save it
Remember 'Save' and 'Save to' are different things.
Have FUN!!!
