Tutorial: Clipping and Masking

This is a tutorial intended to demonstrate clipping and masking in Inkscape with some (hopefully) practical examples. While they use ponies as an example, they are not specific to ponies and can be used for any purpose.
Clipping is a fairly basic operation whereas masking is more complex. I wish I learnt masking sooner, because it would have been incredibly helpful with some earlier vectors.

I do not promise that this is the best or only way to do these things. It is a simply a way to do them. Nor do I promise complete accuracy; these demos show only my experience in the use of these tools.

Download the ZIP file to get a PDF copy of the tutorials, MP4 videos and Inkscape SVG files.
The original MP4 videos without the script is available on SkyDrive.
The completed vectors are available here: CMCs as Flower Fillies, Cadance's Cutie Mark, Detective Twilight Sparkle and Spitfire Hovering.

Reuse: You may not reuse, repost or redistribute the ZIP archive or any file contained within. The vector files contained within were edited for the demo and are probably not suitable for reuse purposes. Use the above links for versions you can reuse.
Addendum: Inkscape appears to have issues with masking if the SVG file is opened in other programs. Consider using clipping instead if possible.
