Love Potion- the name itself should already have you under it's spell! This playful font is one of my new favorites. Created by Hannes von Döhren a couple of years back, Love Potion is such a cute alternative if you're looking to steer away from a traditional style for your invitations. This hand drawn serif font gives a contemporary and sweetheart look while still keeping a clean and legible style. There are so many different ligatures, swashes, and ornaments offered with this font, making it even more customizable for your liking.
