I always get mine from the local art/craft store. Stencil brushes are my most common purchase made from Boar's hair. The often refer to them as 'bristle' brushes. Other styles that come in handy are mop, fan & dagger. Sable (synthetic or otherwise) is much softer but for our use performed similar to horse (although even finer). Often cheaper then many places sell 'detail' brushed and no need to order them!
just pay the 8 bucks for shipping from somewhere and get the brushes, or spend multiple days or hours searching for a better deal...whats your time worth? Help out the company a little bit
but why do you need 6 of the same brushes one just barely smaller than the next? get a couple of these
I ALWAYS help out local small business first! Doesn't take any time at all, walk in, pick up a few, out the door. And I don't have to wait. If I can't get what I want from a local small business then I use those who advertise on this forum.
