I thought "What brings harmony to oneself?" - maybe yoga? And what if I create a card to wish a friend of mine to have harmony while she's expecting?
That's what I came up with. A hand drawn picture of a pregnant lady practicing yoga, and a stuffed tummy on an acetate layer above the card. When the acetate is lifted you can see the card itself: actually the unborn baby is practicing yoga and looking for harmony too =)))
