1. How to resize an image.
2. How to find the layers panel.
3. Getting the Pencil tool to just create a 1-pixel line without anti-aliasing the heck out of it.
4. How to do the same thing with the eraser (which you'd think would be the same process but it never is).
Hope you enjoy and if you have any questions just leave a comment!
