I'm Tori, one of the Pinterest Pioneers in the group and I wanted to encourage you to use one of Pinterest's built in tools!
I've shared about tips for creating Pins before (read: Designing Pins: Text Overlays Do's & Don'ts ) but I know a lot of creators with little design experience can feel overwhelmed with the idea of designing multiple images to test on Pinterest.
The good news is Pinterest makes it easy to test out creating collage Pins right in the platform itself. If using a design tool isn't your thing, Pinterest has you covered!
All you have to do is upload multiple images and Pinterest will add them, giving you the option to create a carousel OR a collage. Give it a try!
This is great to test if you are pointing people to a place on your blog or website that has multiple images around the same topic.
