To cover many of the "texture" lines that were put on the main birch tree, I ended up adding another wash of French ultramarine blue down the centre of the tree and covered some of the marks with the dark patterning on the tree.
The OSWOA shown here is an original watercolour painting using Artist quality Windsor & Newton paint on 300lb. Arches 100% rag, acid free watercolour paper. It is priced at $40.00 and sold unframed.
If you would like more information about OSWOA please go to my post on 12 March 2010.
