The first thing you will want to do is research. Check out other sites on the internet that are selling what you are and see how they network. Do not run out and pay someone to create a website for you, consider blogging first. The best thing about blogging is that it's free and very easy to set up and maintain. Start with Blogger or WordPress, these sites are free and have lots of templates to choose from and detailed instructions on how to get started.
Next you may want to consider setting up a Twitter account. It's also easy to use and you do not have to tweet everyday. It's all about the networking. You can follow others who have similar interests and send direct messages to others who are looking to buy what you are selling. Getting started may take awhile but soon you will find that people will begin reaching out to you and sharing your information.
Another thing to consider is free online websites that will allow you to post pictures of your products and sell them at no cost to you. My Crafty Spot is a site that you can upload photos at no cost to you and they help advertise too. If you want buyers to pay online consider signing up for a PayPal account. It's free and easy to use too. You can place a PayPal button on your blog and ship out items to your customers.
If you need a reason to get out of the house you can find local networking groups to help you either learn more ways to promote yourself or connect with others who know people who would be interested in buying what you are selling. You can order free business cards from www.vistaprint.com . This site has lots of templates to choose from and the first 250 cards are free. Hand them out at each event or send them with every purchase so that the buyer does not forget about you.
It's simple to get started getting the word out about your products. And what's great is you can do it all from your home and online. Free is the key word for all of these sites. Everything you make is all yours. Get online and start promoting yourself and your products and have fun while your doing it.
