You may make some of the best jewelry in the world, but if you can't get it out to your market, your talents are going to go unnoticed. Local craft fairs and setting up tables at collectives and local shops are a good start, but the best way to get your product to the widest possible audience is to set up an online store. Here's how.
Before you decide on anything, even a name, you want to figure out where you're going to conduct your business. Etsy is a popular choice and allows you to set up a shop with minimal effort, but it will take a bit from your profits and you'll have little autonomy over your brand image. Running your own ecommerce site gives you a lot more control, but is also more work and lacks the regular customer visits you get from going with an established marketplace. There is no right or wrong answer - your time limits, technological ability, and product style will all factor in. Just know the advantages and drawbacks wherever you choose to set up shop, and don't be afraid to try your hand at marketing in more than one place.
