Hi Eva,
I'm curious to read what others are doing as well.
My Pinterest page is under my name since I had already had a Pinterest account before I opened my shop. What I recently did to promote my Etsy shop was - I labeled my very first board my Etsy shop name and pinned most of my items for sale inside that first board. I'm going to make an Etsy shop SALE board and put in the 2nd board as soon as I get a chance. I've also made up some boards that specifically include items from my various shop sections since my shop has such a wide variety of items.
I also have an Etsy Treasury board, flower board, recipe board and all kinds of other boards that interest me to help gain followers and make my Pinterest page more interesting. I don't have many followers yet, but I have seen in my stats that I've received searches from Pinterest.
If you would like to browse it or follow any of my boards, you can view it at:
