here I have mixed a half paste of transparent idea gell with titanium white and flake white. I paint it over the dried portrait, making sure it is covering all and deep into the linen pores. Then I take a soft fan brush and buff it until the portrait emerges. I want a good surface to work on. Then I use titanium full strength to reemphasize all the brightest areas and pay close attention to getting the likeness perfected. An artist must see forward and know what she is aiming for. I can’t work today because I have an eye appointment. Diana
