Always disclose your affiliate relationship. Most visitors will probably understand that graphic ad will lead to your getting paid, but if you write a review or use an in-text link as a recommendation, you want your readers to know that may lead to compensation as well.

Advertising. You’ll need to get the word out about your sewing business, and one of the best places to start is with your friends and neighbors. Make sure they are all aware of your services and are willing to pass around your business cards. In addition, you should put up fliers in local fabric stores and get to know the employees so that if someone asks, they’ll be able to refer you. Any business needs a website, and yours will be no exception; you can put up a simple one that outlines what you do, and tells the reader what kinds of prices to expect. Finally, by joining organizations like the American Sewing Guild, you’ll be able to stay in touch with others who are doing the same thing as you.
