Hi Abby,

You need long soft bristles and camel hair or squirrel for fine detail size 01-03 these should be rather short. Long or larger size camels/squirrels will not spring back so you will have hard time painting, long bristles will soften in lime and will work almost as sables in watercolor. You can experiment with Synthetics, but i think they will curl. I use traditional fresco brush set and never needed to change, unfortunately traditional fresco brushes are not sold in US (narrow market - fresco brushes are not suitable for other mediums) TrueFresco.com will eventually offer them through the site after planned big update of the technique section.

For the moment get yourself some long filberts also cheap chinese bristle brushes work exceptionally good (perfect soft bristles), unfortunately these are short brushes and best to be used on small panels.

this is a sample of traditional fresco brush that I use

To everybody: which brushes do you use?
