When sending thanks, it's nice to be able to underline exactly how grateful you are, so that your message feels heartfelt and honest. The parallel stripes in this design serve to add emphasis to the hexagonal badge in the centre, which of course acts as a frame around the words, so no one can be in any doubt that you really mean it.
