I have a vector of a few unicorns that is currently on a blue background:
I want to put them on a white background, but when I do that, the unicorns lose their shape because they are white and don’t have an outline:
How would I add a border / outline to them without having to draw it myself?
I’m looking for methods related to Photoshop, Sketch, or Illustrator.
Group the Unicorn if it’s not already a group.
Then in the Appearance Panel add a new stroke to the group. Click and drag the stroke
in the Appearance Panel, so that it is below the
<Contents> item in the panel.
You’ll then have a stroke around the entire group which you can adjust.
(Old screenshot… but the panel isn’t really that different today.)
Layer Style > Stroke will add a stroke around an entire layer or smart object layer. Although, for vectors using Illustrator or Sketch is probably better.
