Here are some samples of wet on wet painting, a technique taught in Steiner Waldorf schools. You wet heavy weight water colour paper and then paint onto this with water colours. Here is a some more information Wet on wet painting. Sarah tells us that it is about the experience of colour not form.
I remembered a technique I had been shown in one of my very first Montessori training sessions where you add salt to get textural effects!
I did some experimenting with salt on the wet paper. The salt absorbs the coloured water and creates these beautiful feathered shapes. The first pictures have salt…you can see the crystals and then the last three which have a darker yellow, are without.
The salt crystals also add a bit of sparkle if you don’t brush them off!
This would be lovely for Christmas cards.
Have a look at this for more watercolour techniques!
