I've seen things on here about not using "preprinted" thank you cards, which I'm assuming means ones with pre-typed messages that go out to the masses. I totally get that, there's seemingly very little sincerity involved in a generic, photographer-produced "Thank you so much for coming and for your generosity..." without a personalized message.
My question is about using cards from a photographer or other source, without this pre-typed wording. For example, can we use a picture from our photographer of us holding up a "thank you" sign as the cover of a card, (or any wedding picture) and have the inside blank, where we then hand-write our personalized thank you? I'm assuming this is fine, but I would like clarifiction from posts I've seen in other threads. Any input and reasoning is appreciated. "Thank You"
