Covered Jugs and Clementines

Started a new painting, "Covered Jugs and Clementines" 11"x14" oil on linen. I decided to push the drawing towards further refinement before making the transfer on this one. Usually I would stop at the block-in stage, where I'm drawing from point to point with straight lines, but I've decided to step it up a little bit to see what happens. I'm also using a different transfer method than usual. Normally I would trace the drawing, flip it over and trace the back with sharpened vine charcoal and then transfer that to the canvas by tracing again. This time I traced the drawing with a black ball point pen, covered the entire back with vine charcoal, and then traced it onto the canvas going over the lines with a red ball point pen. Then I used brush and india ink to finalize the charcoal lines. So it's a little more exact but there are still some problems. One is that the texture of the double primed linen can make using the ball point pen on the tracing paper a little squirrelly. The other is that sometimes the charcoal can be hard to make out. I was inspired to try this method by the demo I saw on Doug Flynt's blog, but he makes a photocopy of his drawing, then covers the back with raw umber and does the transfer. I may try that on the next one and see if I can get an even cleaner line. I'm trying to streamline my process in order to move forward a bit. Painting is hard enough that I want as many of the cards stacked in my favor as possible before I even pick up the brush.
