Hi I wa wondering if you could tell me a bit more about how to use acrylic? Right now I am experimenting with watering down the paint and thickening it up as I go along but is there more to it than that? I used to use acrylics just really thick all the time and was wondering is that the norm or are there various techniques you have to learn to achieve the results you have here?Sorry for throwing this at you at once but I love acrylics and watercolours and wish to know more about them.
