Unless you are very innovative or artistic and do your own drawings almost everything associated with card making be it CDs, stamps, decoupage, embossing, die cutting etc, is using someone else's art work and ideas.  Even different card folds or making flowers we have probably picked up from watching the TV or reading a magazine or book.  But everything you put on a card and the way it is arranged and organized is your own work and own imagination so in my mind this makes them all ' hand made' - unless you are one of those brilliant foot and mouth artists.   JMO    Lesly
