It is much more commercial in recent history than it was when it began hundreds of years ago. It took on a more marketable characteristic in the Middle Ages. During the 1900s and 2000s, it has grown significantly. Valentine was a Saint in the Catholic faith, although in 1969, he was “down-graded” in importance. Nonetheless, it is a huge financial success for card makers, florists, and candy makers, even jewelers. This is another occasion when creativity abounds. Most all children love making cards for their families, teachers, classmates, and well, close friends. There is no right way or wrong way to make them.

By all means, have fun and tell those you care about what they mean to you.
