You can either use our design templates or you can upload your own design.
All our templates, which you find when you browse our card design collections, contain one text field.
You can edit the text freely inside this text field and align the text how you wish.
(Some cards have 3 text fields, e.g. "classic invitation cards".)
If you click on UPLOAD OWN DESIGN in the top right corner (or go to the design tab under CARDS on the DESIGN tab of your event and click on UPLOAD OWN there) you can create your own card design which has 3 text fields by default.
