@Linda, this is a non-promotional team, so while promoting might be allowed in promo teams, it is not allowed in this team.
I find it best to promote off of Etsy. I have a FB, Twitter, Instagram, and Pintrest. However, I use Instagram and PIntrest the most. I use Twitter and FB primarily when I have new products or am going to be somewhere in person. I use my instagram the most followed by Pintrest. I suggest finding one or two social media outlets and using them and building up your fan base with them.
Outside of that, I no longer pay for advertising, especially on Etsy. They never panned out well for me.
