So a couple of step more forward. Today was more of dealing with the drawing, in particular the fabric under the still life. At first I was being too timid as the pattern is not a solid black. Eventually I decided I would tackle in much like I did with the stripped pattern fabric of the last painting. However this time I have put the darker colour on first. Some of the oranges were removed and repositioned as I progress. In fact you can still see the original position of the bottom right hand orange.  The margarita glass has all but disappeared at the moment as I worked on the fabric design and becoming quite abstract.  Gradually the objects are become more solid as I work with the colour. Next I have to deal with the light.  Still just using acrylic paint but tomorrow I think I will start adding in pencil and pastels (water soluble and soft)
