How can I make some extra money/income over the holidays?

I know this sounds like a silly and obvious question, but I figured it couldn't hurt to ask. I have a job but its an intern position and Im only allowed 30 hours and 8 bucks an hour. Any tips on picking up extra cash for the holidays? I'm trying to limit my output of money (who wouldnt). I'm very artistic and was thinking about making crafts like jewelry and selling them, or using photoshop to make christmas cards (however most people have them already) or doing photo restoration. . I've tried posting and searching on craigslist, but I don't get anything there, mostly bots or quote unquote "artistic photographers" (you know the ones I mean), or people who want to rip you off and get something for nothing. I also entertain at birthday parties but it's christmas so no birthdays, and I'm also knowledgeable at adobe and good at teaching. Any tips?
