Do I have a chance to sell my handmade jewelries?

I love making handmade jewelries, and I want to sell it online, but after browsing through the internet, I found many blogs and websites that are already selling many handmade jewelries,
What should I do to make my blogs known and sell my handmade jewelries?

Try signing up on Etsy. They are very supportive of their artisans and feature them on the main website regularly. Also set up a Facebook and Twitter account, and spend some time putting your website on web directories. Of course, the easiest and cheapest way of advertising is just wearing your jewellery! Give it away as gifts to friends, and make sure to include a business card so that when they compliment your design, your friends have something to give away that refers them to you!
For more ideas on how to market your business I suggest you read a couple of very informative articles you can find below. Best of luck!!!
