The scarf I knit for myself last year was only 11 feet long. That's the nice thing about Four's scarf. It varied in length during his tenure so you don't necessarily have to knit the full 12 feet (or the full 23 feet as is the case with the season 16/17 scarf).

But yes, the sense of accomplishment when you finish something is great. You can proudly say "I made this!"
