A short post on brushes.
Cornelissen in London makes the best bristle brushes I’ve ever owned. They finally have an online store which is great, as getting to central London is a pain and their staff aren’t particularly friendly (I got in trouble there once for checking unfamiliar turpentine brands for mineral spirits and the clerk thought I was getting high). The series 44 are the ones I use. They are more expensive than other brands but they are built like tanks and last forever. Mine usually get worn down to a triangle shape after years of use.
For sables, Zecchi has the best quality brushes I’ve found. The red-handled ‘cat-tongue’ sables are very useful for drawing with your paint. They are also pricey (though cheaper than much of the competition), but will last a long time if properly looked after.
I get asked a lot about brush care. I clean mine about once a week with soap and cold water. In the meantime I keep them in the freezer at night so they wont dry out.
Bristle brushes I wrap individually with a little piece of paper towel to pull out the water and keep the shape. Sables I leave a bit of soap in and make a point with the hairs so they dry with a sharp tip.
