The 2nd best store on Etsy is called ThreeBirdNest and the lady behind it is ALICIA SHAFFER.
She reportedly makes $80,000 a month selling handmade legwarmers, scarves and headbands on Etsy! And she spills the way she does it in a far reaching interview with FastCompany here. Her advice is very good, if you are thinking about, or have ever thought about doing something with your knitting skills. Or if you have ever thought about selling on Etsy. All advice is good.
Go read the interview here.
She has 10 people working for her!
