If you are going to give greeting cards to your loved ones, you do not need to give them generic, bland greeting cards purchased from a grocery store. Instead, you can make homemade greeting cards using art supplies, such as watercolour paints. Giving a watercolour greeting card shows the person you are giving the card to that you care about her so much that you made her card by hand.
Combine different watercolour paints with water in a watercolour palette.
Tape a sheet of watercolour paper onto an art board.
Wet the surface of the watercolour paper with water using a sponge.
Paint the watercolour paint over the wet paper in the forms that you prefer.
Allow the paper to dry completely.
Cut out a rectangle from the paper to measure 7 inches high and 10 inches wide.
Fold the rectangle in half widthways into a greeting card form that measures 5 inches wide and 7 inches high.
