I know there should not be any periods on the wedding invitation itself, but what about the inserts? If we write: "Please let us know if you have any dietary restrictions" should there be period to end that sentence or not? Right now I have a period, but am not sure if it's correct. Also, for the accommodations card, I have "Please make your reservations by X date" without a period. Which is correct? TIA
Re: Punctuation on invitation inserts
As for your original question, yes, use punctuation, unless there is only one (short) sentence on the insert, in which case you can skip it if you want.
My Insert Language:
A block of rooms has been reserved for our guests at X.
Street Address
City, State ZIP
Phone number for reservations
Rooms starting at $X per night for DATES.
Must reserve by X date to receive reduced rate.
Opposite side of insert has directions.
