I made some fan art jokers recently, and I wanted to share the template I created for others to use. I couldn't find a post that already had a template and stuff, so I hope this is helpful.
You have to have GIMP (or other editors that can open .xcf) to use it, but GIMP is free and cool.
Joker Template I made: https://switzerville.itch.io/balatro-joker-template
Use notes: If you draw the joker pixel perfect, scale them up by X8 and paste them over the example. The text box will give you a warning. You will have to use the "Drop Shadow" effect in the filters tab to get the shadow under the Joker's name if you want that.

Reference sheet of all the jokers + goodies: https://www.spriters-resource.com/pc_computer/balatro/sheet/222136/
This ref sheet has the correct pixel size and colors, so it's super easy to just pull from.

(I think you'll also have to download this and import it to GIMP for this to work)

I built some of this stuff basically from scratch, so it's not %100 accurate to the real, official game art, if you're a stickler. Just thought it would be helpful.
If you do use this, please tag me or link to the template, so other people can find and use it. Thanks!
