Thank you John. I have, and used, the masking fluid. Dennis provided very clear instructions on its basic use to protect white areas in early classes.I watch the video on masking medium with interest. Always fun to hear about more advanced technique which may be use in the future. I noticed that the red bleed a bit in his yellow on the demo, probably what you hitted by touch and go in your experience.If I understood Dennis well, when you have a dry edge, you can put water at a little distance from that edge and move it slowly toward the edge. Then by 'rubbing gentle' the bruch on the painted edge you can soften it. I leaned this very recently, so it would be in the magnolia or one class before, in the recommended order.Again thank you, most appreciated.
