Interior Line Drawing

It was fun working on my latest interior line drawing.  After completing the contour drawing below, I added a variety of pattern and texture keeping a low contrast of value. As each pattern was drawn, there was just a small gradation in the change of value.  The variety of patterns on the pillows was added first, next a light, simple geometric pattern was drawn on the sofa.  The flooring also has a small gradation of value with lines showing the wood and simple, light patterns on the rug.
