How to add object outlines?

I want to add a border to an object to create a webtoon, and I studied a lot of clips, but it’s an old version. Do you know how to add a border to an object in version 1.97?

Maybe try sharing the link to the video so we can see what you’re wanting to do?

This one, I tried to do it and it was really difficult. It was difficult because I had to make many objects T_T

I did it. Thank you for your help and concern. >3
