Punt of course. I started on a new painting while the other rests. After I had laid in the wash I decided I wasn't thrilled with the composition. Funny, because I had considered the question while I was drawing it and decided I wanted to keep it. But, after blocking in, it looked too confusing. My brain was screaming "Shared line issue, shared line issue", so I listened. Perhaps you have never run into this problem...but you will. So give it a shot, erase your guidelines and try to fill in the space with a matching wash. We are talking about a large space here folks, not an inch or a leaf, I'm talking a foot wide. Nope it doesn't work. there is a tiny overlap, the color isn't perfect, etc., etc. So you consider your options. I considered a gouache wash, but wasn't convinced it was the look I wanted. For a small space, I might consider a scrubber and some stippling work, but again, this was huge. So how did I fix it? I taped it all off, which was considerable with lots of curves, and used my Mr. Clean Magic Eraser, only slightly damp, and cleaned off the entire area. It worked like a charm. Some slight color adjustment and voila, back in business. Hope you can use this tip. Back to my brushes.
