It’s best to have natural fibers, like Hog hairs – 100% Pure Hog Hairs = No Shedding.
Make sure to have some paint thinner nearby while working to help keep the brushes clean.
Don’t let them get gummed up.
With care quality, brushes will last many years.
It’s handy to have a large selection of brushes like the one in this kit: Fan: Size 4, 8 Flat: Size 2, 6, 10, 14, 18, 30 Round: Size 2, 6, 8, 12, 14, 20, Flat Brush: Size 5.
You’ll get more of the ones that you enjoy using most.
Decent brushes require love and maintenance. Don’t leave them soaking in thinner past the time you are painting. Take them out after shaking as much pigment out in the thinner as possible. Then wash them in warm water with mild dish soap and always leave them hanging with the brush side down. If you don’t have a fancy holder, then attach a loop to the end of each handle to hand them.
If you are starting out, you can often get cheap brushes that become unglued and shed their bristles easily. If that’s ok with you, go for it.
