Make festive and personal cards with bubble print! METHOD: Start by protecting your work top with plastic sheeting. To each of a few bowls add 1 dl water, a pot of craft paint and 1 tablespoon of washing-up liquid (like Fairy Liquid, which bubbles up nicely). Place a drinking straw in the mixture and blow up a little heap of soap bubbles. Take care to blow your bubbles carefully to prevent spills and splashes. Place the face-side of the card down on the bubbles to produce a cool bubble print on the card. Repeat a few more times and using different colours for a festive effect.
