Purfling installed on 4 plates (2 fronts, 2 backs) and now working down the arching. Here is a spruce viola top. Parallel gouge marks from the rough arching. Smaller (aka smoother) tool marks around the purfling now, smoothing out the perimeter. Starting to take the gouge marks along the spine out with finger planes. Then onto scrapers. Then onto horsetail. Smaller shavings with each successive tool.
