Aaron HeWelcome to the shop!
I don't really have a formal name for this enterprise, as designing playing cards is purely a hobby for me.
I also don't really have any money, so I've just been using Inkscape (an open source illustrator-alike) and my mouse/keyboard. No fancy-schmancy tablets or pens or studios either, just my desk in my bedroom and my trusty laptop. I pride myself on spending a lot of time on my designs, and even though the artwork isn't super detailed and the indexes/suits may be a little rough around the edges, be assured that the art in every deck you buy is full of love!
Though I highly doubt anyone will, feel free to draw inspiration from my work without having to worry about anything copyright, just don't outright steal anything.
Have fun browsing!
