Traditional tented escort cards are perfect for all types of wedding receptions, formal & informal. Table assignments can be written on the front of the card or inside the card, along the bottom edge.
For place cards & escort cards, I always recommend using first & last names only (no titles). The names are easier to balance on the cards, and I think the cards are more pleasing to the eye. Excluding titles is not considered less formal, and it’s easier for guests to find their names without the addition of titles.
