Maybe you know this already, but it was a fun discovery for me. If you want to see if anyone has pinned something from your blog go to this site:
EXCEPT replace the yellowblackbird address with your own and voila!
Unfortunately you can't do that for Etsy shops. Pinterest doesn't categorize Etsy shops separate. : (
It's really fun! I love seeing what people have pinned from my site. A couple of you have even pinned some of my outfits which is very flattering!
It's also great if you find a blog and want to quickly see what projects or outfits that person has made. I love seeing what's been pinned from Kendi Everyday or Sunday Crossbow. It makes for a great look book!
