Scanning? Well, do you have Paint? If you do, you can draw the picture in blackandwhite and scan as TEXT - makes everything pure black or pure white! Then you can use the fill bucket to just fill in all the shapes easy! From there it's not hard to add basic shading if you want it. If you don't have paint, search the net for the GIMP or Paint.NET (might be PaintNET) - both of which are free to download and use.
I actually have Adobe Photoshop. The problem is, I have so much at my fingertips and don't know how to use it! I do like you're idea of scanning it as text. I'd given up coloring traditional art on the computer 'cause the line art always looked like crap. Instead, I've been using it as guidelines to trace over.
So, thank you! I'll definitely try that in the future.
You're welcome! Just make sure that the lines are as clean as possible - you can always neaten them up a bit later, but if the paper is too rough it will be too hard. Ohh, and if you have Photoshop and want to keep the lines, set layer mode to 'Multiply' (see drop-down just above layers, willbe called 'Normal' to start with). Then paint (with paintbrush) under it. If you want to make the lines darker, hit Ctrl+L (or Mac equiv) then drag the black arrow on the slider up a bit to make lines darker. Or you could paint over the lines on a separate layer, then delete your lines.
