I see many amazing work of avatar, signature etc, but, Many people don't add borders which makes avatar, signature etc looks like incomplete. I'm here for a "basic" tutorial how to add border in a few steps!
- Open your image. (I'm taking a 140x140 White color for example!)
- Click CTRL + A. (Select All)
- Go Edit -> Stroke -> Width (your choice, I'd choose 1) -> Color (Black) -> Location (Inside!) -> OK
- Click CRTL + D. (Deselect All)
