GNU Image Manipulation Program (GIMP) is a free and open-source program sharing much of the functionality of paid software such as Adobe Photoshop. I have used it for many personal and professional projects, and continue to learn how to achieve more each project.
I have much experience using the path tool to both post-process cluttered images and create SVG files for use in CNC operations and CAD work.

I've made use of the path tool to extract portions of an image, to use as a foreground layer.
SVG paths exported from GIMP are great for CNC lasers and vinyl cutters like Cricut devices.

Vinyl stickers can be made by layering outer silhouettes and details.
I organize all my work into layers, and my layers into folders. This makes it easy to move and edit relevant content together, and avoid altering things I want to stay the same.
Using layers to link group all foreground elements together, layer the cards beneath one another, link shadows to their card faces, and control opacity of background layers independently.
