Jehanette de Provins, Her Majesty the Queen of Northshield, teaches classes on how to create armorial images using GIMP and images from the Book of Traceable Heraldic Art, and recently recorded a session for viewers at home.
GIMP is an open-source software package for pixel-based illustration, in the same vein as Paint and Photoshop. As a Mac user, I find the interface to be a bit clunky, but it’s free, it includes a lot of features, and it runs on a wide variety of operating systems, which makes it a useful tool.
