We sent thank-you cards to everyone before the wedding for all the pre-wedding gifts we received (from showers, etc.). We used a simple thank-you card we purchased in a box of 40 - they just say "Thank you" on the outside and are blank on the inside. There are some flourishes on the front. We wrote our own personalized thank-yous inside each card.
I still have some of those cards left from the boxes we bought before the wedding, but I am hesitant to write thank-yous using the same cards we sent before the wedding. Obviously, each would be personal, and we'd write thank-yous for coming to the wedding, etc. (they'll be different than the cards they may have received from us before) but we're not sure if this would be seen as cheap or inconsiderate because they're the same standard cards.
What do you think? Should we buy different thank-you cards to write our thank-yous, or can we use the ones we've already sent before since we still have some left? Thanks!
