Business thank you handmade card

If someone does something for you or gives you a gift, traditionally a note of thanks is sent to the giver to express your gratitude, a thank you card may seem like a small thing, but it carries a big message of appreciation and gratitude more than any text ever has.
The cover of the card is half black and half white, which looks simple but has a sense of design. In the middle of the cover is the gilded "thank you", which is the finishing touch of the card. You can also open the card and write other words in the blank space to convey your thanks and blessings.
