I love to work with acryl paints mostly. Occasionally I also use watercolour. Both have a different approach. With watercolour, of course, patience and layering are key. With acrylics you don't have to be as patient and you really can dive into a piece of art for an entire afternoon. Those are my favourite to do, but watercolour is elegant and at times surprising when it comes to the results. And that's pretty cool too :-)
