A best friend....
I really love my paint brush. This guy has been with me since I started my painting furniture venture.. His bristles are broken in and his handle is covered in paint. He is a few years old but I looked at him sitting on my kitchen counter and had to relay the message about how a great brush can do such great work. To me it makes all the difference in the world. We have been through a lot together, but he has always made me happy.
A good brush can last a lifetime if you take care of it.. I just wash mine out with water but you can use mineral spirits or just soap and water too.
My brush is a Wooster
Shabby Love also sells paint brushes by Annie Sloan in the retail store and they are quite amazing!
So stop Buying Cheap brushes and go out and make a small investment, It's So worth it and you can see the great results every time!
