How to list a Personalised product in Handmade?

Does anyone know if you can list a ‘personalised’ gift, where a customer has send you their personal wording requirements in text form. I offer a personalised Baby birth frame, where I add name, date & time of birth, and weight, so the information I need is personal for each frame.
I’ve added ‘variations’ ok before, but that info is set wording that doesnt need to be changed each time.

I cant seem to find the answer anywhere. Anyone help??
