Tips on how to make just $70 by selling my knits

I want something for my birthday but my parents said they’ll only cover 200 and that I need to somehow get another 70 by myself. I’ve been knitting for 7 years and have never sold anything before, and was wondering what I could sell. thanks!!

Take a look on etsy and see what kinds of things are available. I would think ski hats, fingerless mitts, cell phone sweaters might be popular.
