DEEP IN THE JEANS SHE'S WEARING
Title says it all? How the hell does one create a fursona? What's the process for making a 'sona?
There is absolutely no one simple or "correct" method. It's literally just like creating any other character. Whatever gets you to a character you enjoy is what you do.
This, I think, is the main thing that should be kept in mind. Don't compare your character to others, and don't measure your value by theirs.Remember that this is YOUR character - it's not meant to be a popularity contest, and it's not meant to be a competition for whose character is the most colorful or edgy or powerful or sexy.
