PLEASE! Do not re-invent the wheel with anything business related - including Pinterest!
Here are some amazing resources.
This is the bible! For serious :)
This is the Facebook group by the same team that produces the Simple Pin podcast - their Facebook group is free and is a great way to connect with other bloggers.
Seriously the best tool for Pinterest - with Tailwind, you can schedule your pins ahead of time - like MONTHS ahead of time, so you can focus your time back on your business!
What I highly recommend for creating pins! Search for “Pinterest” to find the correct Pin dimensions (it’s 2x3 not the really lonnngggg pins that used to be popular) - as well as all of their free templates to create beautiful pins.
If you need more pictures than the free ones on Canva.com (if you’re not using the paid version), I highly recommend using Unsplash for great free images!
