I would like to start a thread to help cross promote each other. The easiest way is to write a post about the person's shop above you on your blog.
1) Make sure to put the shop name in the title of the blog post.
2) Make sure to put a link to the etsy shop in the blog post.
3) It would be helpful to share the blog post to your facebook, twitter, pinterest, or social media outlets.
4) Send them a convo via Etsy.
Since I am at the top I will write about the person who is below me.
For the rest of you, Write about the person above you.
Cross promoting is key.
