I need to vent. Every tutorial I see of this has a perfectly scanned picture, which makes it easy to outline, but my scanner is horrible. I have fat shade lines on the edges and when I try to do grayscale or contrast, they just turn black and interfere. Is there any way to just make it black and white, outlined, and get rid of that scanned shading?

Hmm, I had a look in your gallery and I see what you mean. For me that only happens if I'm using paper larger than the scanner, or if the scanner lid is not properly closed... is it either of those things? What model of scanner are you using?

A temporary fix would be to try drawing on A5 paper, or don't fill up the A4 page, so that you avoid the areas where the scanner has issues. It's not ideal but it's a start...

Yeah, The paper was 9x12 and in my sketchbook, so it was both of those. My scanner is just the scanner feature on our printer, but I would like to get a real one. What exactly is A5 paper? Anyways, this has been very helpful, thank you so much!
But I would still like help with the above questions.

the most common paper is A4, which is 8.27" × 11.69" (so probably your sketchbook), every time you half the size, the number increases, so A5 is half of A4 (5.83" × 8.27"), and A6 is half of that, etc... while A3 is twice the size of A4, A2 is twice the size of A2, etc.

Your scanner is most likely A4, so that should be fine, but having the paper still on the sketchbook is likely the major problem.
The reason for the shadows is that to take a 'photo' of the paper, a scanner blasts light at the paper, and records what light bounces back, but in areas where the paper is not flat on the scanner some light escapes so the scanner sees those areas as being darker.
So that's the key: paper is completely flat on the scanner.
If your scanner has a lid, you usually use that to make sure the paper is flat, but obviously you can't if you've got a book.

Thanks, that's actually really helpful, but it'll be hard to actually rip them out of the sketchbook. It's like I'm throwing them away...

I have one of these: [link]
For storing everything that has been scanned. I also have one for storing all the pictures I want to redraw and then scan. Then you're archiving them, rather than throwing them away

That... is another really good idea. I really need to man up and deal with those problems, even if I'm a girl!
