So I am creating this T-shirt design, and I want to create an inverted effect in a way that doesn't require me to split the design in half, make edits, then seam them back together.
The way that I got the example is using the slice tool and then exporting the two halves, making my edits on one of the halves, putting the two halves back together, and then image tracing to make it vectorized again.
This method sucks because it ruins the font that I was using, and there is now no way for me to make changes to text or anything like that without completely redoing the design. There absolutely must be a better way to do this, but I have no clue as to what it is. Thank you so much to whoever answers this.
