Inkscape is a drawing program that creates vector graphics, or shape objects. Which is different from pixel graphics where the image is made from a grid of coloured dots. It has advanced functionality for creating professional artwork. Inkscape is a free, open source program. So if you want to try it you can download it from inkscape.org and install it right away.
I used Inkscape to design our wedding invites. They were a bunch of “cards” made to resemble a board game as we both love board games. Fun times!
