Hi hoping someone can help me out here

My MIL is really getting into the watercolor painting and we were thinking of buying her a really good set of brushes but don't know which would be a good quality brand?

I think sable is the best hair? But theres so many sable brushes that we can't decipher which are good quality and which are not.

Would anybody know of a few good brand names that we could check out?

She also does oils and acrylics so we are looking for a good all rounder,

Thanks a bunch!

I love sable brushes called Prestige by a company-Grumbacher but I only do oil painting. I also need a few nylon detail brushes because sable is very soft. I don't know if these are available where you are or not.
My painting instructor told us not to mix our brushes. Oil brushes for oil painting and water color brushes for watercolor. Using too much water on an oil brush may cause it to loose the shape of the bristles.
Your best bet is to buy them in an art supply store and not in an arts and crafts store. Usually the clerks that work in the art supply store know about the materials and can guide you to the right choices or maybe you could contact her instructor if she is taking lessons.

funcakes thanks a million for your reply
