Comics created using the wonderful
vector graphic program
Inkscape.
If you want to explore making vector graphic cartoons on your own,
download and install Inkscape which works with Windows, Macintosh and
Linux. It won't cost you anything. It is Free Open Source Software
(FOSS).
Then, if you want, download one of two design templates listed below.
Right click and choose the "Save link as..." option.
Basic betty'n'bob template - three panel
cartoon template and some starter characters.
Instructions template - three
panel template surrounded by some instruction material for how to do
new characters and cartoon elements.
(Right click and choose the "Save link as..." option. Templates [SVG
format] require a program like Inkscape.)
Have fun. Learning is a game that pays you many benefits.
