How would I overlay a graphic (a logo in this case) on a t-shirt and make it look like it’s really there, not just superimposed (wrinkles, lines, etc?) I don’t have photoshop or any adobe software, unfortunately, so a GIMP solution would be best.
Answer
If it’s a white t-shirt and the logo doesn’t have white parts that need to be visible, then you can just go to the Layers panel and switch the “Mode” setting to multiply.
