Have come across a lovely idea, a pamphlet called 'Ten poems About Mothers', and the idea is that you send it instead of a card. Cards get thrown away but this is to keep. The people who produce them are called Candlestick Press (www.candlestickpress.co.uk). They have some lovely 'not cards' on other subjects including Puddings and Love. :) Anyway, a lovely solution for something special for mothers' day.
Human Affection
Mother, I love you so.
Said the child, I love you more than you know.
She laid her head on her mother's arm,
And the love between them kept them warm.
