I have painted with the new JOSEPH ZBUKVIC brushes for about three hours so its early days for a real assessment but my first impression is that they are quite magnificent. I am looking forward to the next dozen paintings completed with these brushes when I expect to have a better perspective of what can be done with them in my style of spontaneous transparent watercolour.It was fortunate that I stumbled onto Joseph Zbukvic recommending them on U tube.
