Setting Gimp Up for Pixel Art
1) Edit -Preferences
Tool Options
Scaling
Default Interpolation - Set it to None
2 )Manually set all tools with threshold (marquees, lasso tools, scale and rotate tools, etc.) to 0.
3) When doing pixel art, DON'T use tools such as the brush tool, smudge tool, airbrush tool, etc. If you plan on submitting your art to deviantart groups there is a chance your art will be declined for such things, as those tools are not pixel art tools.
4) When doing pixel art only use the pencil tool and the eraser tool set to hard edge. Make sure both the pencil tool and the eraser tool are set to 100% opacity, you don't want any stray pixels anywhere.
