In the craft world, especially sewing, there are MANY facelss and voiceless videos demonstrating how to sew stuff. Many of these YouTubers are from other countries and don't speak English. They are some of my favorite videos to watch because they get straight to the point - demonstrating how to make something without a lot of chatting and explaining. So instead of watching a 20-30 minute video with someone explaining what they're doing, these videos usually run 10-15 minutes, but still provide everything I need to know to successfully complete the project.
