I initially had a personal account for personal pinning (not sure if there is a different "business" account). I followed all of my facebook friends and created different boards, like DIY projects, home decor, fashion, recipes, etc. I created a board for my shop and pin different items from my shop, usually new listings and blog posts, but I try not to do a bunch in a row. I mix it up with my other pins. I've definitely had things re-pinned to DIY boards, but I figure people are always going to attempt to DIY, but when they realize they can't or don't want to, they always have the link to my shop! I usually get a few views from pinterest after I pin something from my shop, but nothing overwhelming. I figure it's worth it for a little bit of extra exposure, and I've found lots of other fun things on pinterest as well!
