What It Is: Do people ask you your secret to perfect pie crust or how you made that wreath? "Everyone knows how to do something, or has a hobby they enjoy," says Kimberly Lawson, owner of OohLaLuxe.net, who has created fashion and beauty tutorial videos. "These can easily be turned into profits." Simply sign up for a free YouTube account. Then use a smartphone or digital camera to record yourself explaining and demonstrating how you work your magic. (If you're more tech-savvy or have a burgeoning teenage filmmaker in your house, you can use desktop software, such as Windows Movie Maker, to create a slicker video.) "Once you upload the video to YouTube, enroll in its partner program," Lawson says. YouTube will then place ads inside or near your video, and you will earn money from the ads themselves, video views and click-throughs. "The key is to put a unique spin on your video," says Lawson, especially if there are lots of others on the same subject.
