I know how hard promoting can be, so I have a suggestion for you. This can be very interesting and it can bring to all of us more traffic and sales.
I would like to promote some of your products on my blog.

Here is how it works: if you have a white colored product in your shop, just post the link above in the comment. I'll post the picture of your product on the blog and by clicking the image the visitor will be directly sent to your Etsy listing.
Also I will promote them on all of my social media platforms (twitter, instagram, pinterest, tumblr, google+ etc. )
I will post the link of the post here and you'll be able to see your products on the blog. Also, you can repost the post with your products on your blogs or other social media platforms.
I love coworking with other Etsyans and my idea is a way for sellers to gather together and support each other's shops.
Let's have fun and make some sales. :)
