The best way to sell your work is to just get ‘out there’. If you have local venues, like craft shows or small art fairs, do those first. Usually getting a table at a venue like this is not expensive. This way you get out into the public and meeting collectors and buyers face is face is invaluable. You get to see their reaction to your work, you get to talk with them and you will learn lots about what you have, where you need to improve, what your strong points are. Their feedback will give you the incentive to get going further.
The next step would be to set up a blog or website and put your work on there. This way you can use social media sources to further promote your work- Twitter, Facebook, My Space, LinkedIn, Blogspot.com, all are ways to network and get your work out on the net. Websites are a little more cumbersome to keep updated, but your Facebook page, or your Blog can be updated easily. Keep things fresh and you’ll be surprised!
You can also use direct sales by embedding a Paypal button right in your pages. Go to Paypal.com and follow Selling Tools to Create Payment Buttons for your Website for more information.
