If you know someone getting married soon, how about giving them a set of wedding thank you cards or some personalized notecards or address labels?
With all that the bride and groom will have in front of them when they get back from their honeymoon, why not have a set of wedding thank you cards personalized with their return mailing address on them so that they can send their thank you cards with no hassle.
Would it not be nice for the bride to spend more time crafting a thank you note on her personalized notecards, rather than worrying about getting the wedding gift notes and then delaying her thanks for all of the gifts received?

Wedding address labels are fun to customize, personalize and send to friends! You can also make some fun wedding book labels for those special personalized wedding book gifts.
