I absolutely love helpful information like this! I was searching for fonts on Pinterest and I came across free font pairings. I found a couple of sites that have the fonts available for download.
Sonrisa Studio collected a great selection of font pairings. You can visit the link to view free font bundles.
Skyla Designs is another helpful site that I found through Pinterest. Skyla lists 5 different font pairings. When you visit the site it will allow you to sign up for the newsletter.
Hygge Design has gathered up 10 beautiful font pairings. These are all free fonts as of right now. Be sure to read over the TOS before using the fonts for commercial use.
