I have noticed that my sales seem to come in groups. I don't know why. I don't make any and then I make 3. However, I have noticed that the amount of people looking at my shop has steadily increased since I started using Pinterest.
I have 12 active boards. 10 of them are things that I like or I do (example movies, tv, books, places to visit, places to eat, etc.) The other two are Etsy shops mainly. One board is my shop and I try to post 3 new things each day. The other board are things that I like from other shops. Many people have repinned from both my shop and the other shops. Getting my shop out there in the public eye for new people to see it.
