Mechanically, it can be done using a text form field. Aesthetically, you'll be frustrated by the inability to control the field's font.
Thanks, John. I was afraid of that. Any suggestions for another app?
How about Adobe Acrobat Pro XI ?
You’re better off giving them a Word file.
Design the Invitation.
Create a word file that has the name for the invitation in the correct size and location.
Print the names.
Then reinsert paper - then print the invite (or vice versa - whatever works).
Simplest and easiest method really.
Or buy pre-printed paper. There’s a ton of varieties to choose from.
