Custom Stationery & Branding Process

Our story

On Three Designs is owned and operated by Alicia Lantzy. The company began in 2013 with very humble roots out of the attic of her home in South City, Saint Louis. The business has since blossomed, outgrowing our South City space and moving into our new design studio out of Clayton, Missouri in the Fall of 2022.

On Three Designs specializes in custom stationery and branding for wedding, events and all of life’s milestones. We’re committed to designing luxury experiences through paper that feel as unique as the couples that they’re made for.

Custom Stationery and Event Branding

Artwork and Monograms

“I cannot say enough amazing things about the impression the stationery we created with On Three made on our guests! Everything from the invitations, place cards, menus and day-of signage was STUNNING, and most importantly, unique to my husband and I. The team at On Three, specifically Laura and Alicia, did a great job getting to know us and understanding what was most important to us. Everything we dreamed up, they turned into a reality. We are not the most creative when it comes to design/concept, but the On Three team was flush with fun and unique ideas - many of which, we ended up using! When invitations went out, I received tons of texts from guests remarking how show stopping the invitations were. They set the tone for what would end up being an incredible weekend, and I could not be happier with our experience!”
