This is a card I created for a Technique Class I held the other week. It uses the Black Magic Technique.
To create this effect you simply stamp in Whisper White ink onto Basic Black Cardstock (tip: make sure the white ink is dry before proceeding - a heat gun can speed up the process). Then using the Stampin' Up! Watercolour Pencils I coloured in the image. Using multiple colours gives more depth to the image.
