I am doing a lot of brush practice, and bought a Portable Palette, and a couple of new colors to add to my Winsor Newton collection. Sennelier Serpentine Genuine, M. Graham Magnesium blue, plus later I added a chrome green. I realized after I loaded them all that the wells without the cups would be just as workable, once I get the colors decided. I am mostly using them to highlight and color passages in my written journal, brushwork, slowly moving to sketchbook pages. I have so many! nearly empty sketchbooks to fill, and so little motivation, ideas, gumption, whatever.
