How much does an Etsy account cost?

I'm going to sell crocheted items like cellphone holders,belts, amigurumi's, and motifs like flowers.Just want to make some extra cash. Not trying to get rich. I already sold 100 flowers to someone on the internet for 27.00. so I know I can have some success. Just was wondering how much the fees are at Etsy before I start. Thanks in advance.
