Thank you cards are sent to people after they have done something special for you like attending your wedding, the baptism of a child, a housewarming party, a birthday party or even after you have enjoyed their hospitality and returned to your own home. These are the times when you have to send people a thank you card or a thank you note. Showing your appreciation is a must so that they feel good about taking the trouble to attend your function and also extending their hospitality to you.
If the number of thank you cards is for an occasion and there are a lot of people you have to send these to, then it is best to plan the words well and get the cards printed. If it is for an occasion like a wedding or baptism, you can have photo cards made with either the bridal couples picture on it, or if it is baptism the bay's picture. For other occasions select a nice design, could be something elegant in white and gold and make the receiver feel really special.
Thank you cards are also sent out after bridal showers and baby showers to all the guest who participated in the event and made it wonderful. If you have gone and stayed with friends or relatives in another town you could send them a small gift along with the thank you card. A bouquet of flowers would also be nice along with the card.
There are often occasions in the office where someone has assisted you with your presentation or something which you had to deliver within a stipulated period and could complete this only because of the help extended to you by your collections. Your colleagues would feel much happier to extend the same help to you again if you recognized their efforts and sent them a thank you card along with a small box of chocolates or some token like that.
