I started this with a light blue watercolor pencil on Arches 300 lb watercolor paper (I taped off an area of about 9x11")
here using only Kimberly Watercolor pencils (of the 12 colors in the pack I used ten, not using light green or lemon yellow.
It rather looked like a colored pencil drawing at this stage, before any blending. On the lightest parts, I only used a few light strokes of straw.
Of course, my inclination was to start with the darkest darks but reason took hold (this being a watercolor) and I did the lightest lights first. Kind of interestingly (to me at least) is that I only used one brush -a Lowe-cornell 10 ultra round (7020). It has an excellent point on it and yet could do the nicest bit of wide swatches.
Now I need to get over to deviantart and thank Chamberstock for this portion of her purplescarf pics. She has lovely stock photos.
