Hi Teoh. I am a relatively new watercolorist and have found your blog and youtube channel very informative and entertaining. Thanks for all the great videos and keep doing what you are doing. Your topics are great and I don't think you need to change a thing. I have ordered an Escoda Reserva size 6 brush and am very excited about receiving it. I only found this review on it after placing my order, however, I think I have made the right choice. This will be my first sable brush and if you have any advice when it comes to choosing Sable hair brushes please let me know. If you could only have one, which brush you would choose and why? Kind regards, Mike Patrick
