When Background is Unimportant

This young girl was seated in shadow inside a cardboard shipping box. SHE is important, but the shadows inside strictly represent darkness for which no special attention is warranted. All that said, the thread choice for the background is the same value and color as the painted surface. Selecting same value/color permits the thread to nearly disappear into the background. The quilting pattern chosen was a simple micro stipple which also draws no attention... it's just there.
