These are a DIY project, so you’ll need to print & trim yourself, but it’s a mere $3.50 for the printable pdf, so you can make as many of them as you want! (Just enlist the help of friends or bridesmaids for a wedding or large event!)
P.S. Don’t have time for DIY? Check out Timeless Paper (also on etsy) for similar place cards that are ready-made, plus visuals of another option for displaying these within place settings.
*Update 8/18: See Brigette’s comment below regarding the free extra goodies!
