Do a lot of research!!! I follow blogs about Marketing Small Business, view FB pages websides etc from other sellers, what do they do to get all the sales and views. Look at art, paintings, nature, go to museums, watch movies, listen to music. Listen to customers!!! Read fashion blogs and magazines to keep up to date of the trends and styles. I know that if I stay in my studio at home, my inspiration will drop, going out and read and watch and use all my senses helps my right side brain. I am a very visual learner, like probably a lot of people who are sellers and creators, that's how I learn and think, and do:) Love Pinterest for that reason.
What is your secret?
