This is an interesting packaging concept used on the wedding invitation boxes. We are going to tie the knot. In the greek language, there is an expression that uses the word &ldquohang&rdquo in order to say &ldquomarry&rdquo. So, traditionally, when the father of the bride says &ldquoi will hang them&rdquo, he means that he will tie the couple with the holly bond of marriage. This tradition inspired a humorous invitation that includes both a rope and instructions on how to make a slip knot.&rdquo the interesting graphics are used on the box to show the knot.
