Along with a few varieties of small synthetic brushes, I've been a fairly loyal user of Winsor and Newton series 7 miniature and regular series 7 for several decades by now, yet over the years I've observed that the amount of hair in the ferules has decreased, the cost has gone up, and although they are still good brushes, for the price and quality I'm just not feeling 100% satisfied with their performance and staying power.  With all the interesting brushes out there to try these days, I thought it was time for some research on sables.  After looking over three or four lines of brushes, I decided to try Da Vinci Maestro Kolinsky 'Miniaturist' sables.   

My rationale was that of all the miniature brush lines I saw, the Da Vinci Miniaturist line has more hair (fatter at the ferrule, or base of the brush), and a shorter but still very pointy tip.  It's a round brush made of Kolinsky sable, (which means male winter Siberian Kolinsky sable, the best sable you can get), and I hoped a fatter pointy brush meant it would hold more paint without dripping, and give me more control and precision.

So far I am very impressed with these neat little sables!  Above are some comparison pictures demonstrating the difference between the two lines, especially since the brush sizes do not exactly correspond, and it took me a while reading over the brush dimensions provided online to decipher the sizes I wanted to try.  They are not inexpensive, but I got mine through a nice sale at Dick Blick online.  I've been using them on a commissioned miniature painting in egg tempera, and also on a larger portrait commission in oil.  As soon as I get a little further with the miniature commission, I'll post it in progress.
