Custom decals for an uneven surfacE? (action figures' chest)

Posted in Custom Workstation

Hi everyone,

Since I wanted to mod a Sinestro Corp Sinestro Variant DCU figure into a Red Lantern (new head, etc) - I wanted to know:

Does anyone know of a good tutorial (with references to what materials) that shows how to generate a custom decal using a home inkjet printer?

I'm terrible at drawing circles/emblems (I need better paint brushes for starters), and being able to design something in photoshop, scale, print and apply it would be fantastic.

Thanks in advance for your suggestions.

Cheers,
-Blayne
