Answering this question is a lot like answering the question why making your own gift that you will then give to someone on a special occasion is so great. There may be tons of reasons behind this and we might spend days talking about them, but the real thing is that the main reason handmade greeting cards are so great is that they show that you care and that is what greeting cards are all about in the first place.
There are many people who have forgotten about this due to a number of reasons. For instance, they might have sent out too many greeting cards and other cards that were considered appropriate in a number of situations. And when you repeat an action so many times, you tend to forget why you were doing it in the first place. When it comes to greeting cards, you do it to show that you care. You do it to show that you are thinking of that someone and that you have certain feelings towards them and towards their occasion.
Now, sure you can buy greeting cards that will be perfectly appropriate and that they might even enjoy and not consider as yet another greeting card. This is especially true today when you can get all kinds of greeting cards online. But the truth is that a handmade greeting card tells volumes. It tells that you wanted to set aside the time and the effort to make it, which only proves that you care and that you are thinking of this person. It also shows that you are ready to put your creativity to the test just to make that someone something special.
Furthermore, a handmade greeting card also does something that a generic card can never do. It can be entirely personal and as appropriate and emotional as no bought one. For instance, imagine that it is your mother’s birthday. You can buy literally innumerable different greeting cards just for this occasion. But now, let’s imagine that you took a few photos that you have with your mother from various points in your life and you make a little collage of them, complete with a text that you will come up with and that will also be as personal as possible. Doesn’t it make for a much better greeting card and one that will truly make your mother understand how you feel about her?
