Here is a great tutorial that both young and old can do, by the talented Arounna Khounnoraj for Bloesem Kids. The pretty water colour and crayon resists each other and makes for a colourful piece of art to frame or just peg on your childs wall.
What you will need:
*watercolour paper or heavy stock paper 8 x 10 in.
*crayon (white is nice – I used grey)
*watercolour paints and brushes
*cup for water
..Take the crayon and do a drawing on the paper
..Cover the entire paper with just water (this is a wet on wet method)
..Take the watercolour and paint over the entire surface – the crayon will resist the paint and stand out nicely showing the drawing.
Let stand to dry.
