Hi,
I know that some folks were talking about advertising designs on Pinterest and I agree that it is the perfect spot to get traffic to your website, blog, or shop. If you aren't familiar with Pinterest, I have a guide that you can download to help you figure out how to set up your account (with links to Pinterest help).  
It is part of a resource library that I created to help other artists, designers, and freelancers. You can get access to it on my website (lisamgriffin.com) or go through the link below to sign up.

I have used Pinterest for my freelance business and seen a big jump in traffic from that platform vs others. Especially with Instagram being fussier with the algorithm this past year.  
 
I would love to hear what you guys think of marketing on Pinterest vs other platforms.  
Happy Creating!
Lisa

FB has more users than Pinterest, BUT pins have a much longer "shelf-life" with Pinterest being known as more of a visual search engine. Which is perfect for creatives and artists to share their highly visual work!  
The half-life of a Facebook post is estimated at 90 minutes, on Pinterest, it’s 3.5 months!
 
Pins are far more accessible than Facebook (and Twitter) updates. Pinterest gives its users more opportunities to find content, and those opportunities are what increase the lifetime value of pins. That said, if you prefer a platform with more of a social component then FB or IG would be the best spot for that.
