Was going to start a restoration of an old brush that says Badger & Bristle on it. Was wondering if there are any sources for a mixed knot like that. The hole is 20mm and the loft needs to be 50mm. I've seen Badger, and I've seen Boar but can't seem to find a mixed knot at any of the usual sources, i.e TGN or Whipped Dog. Anyone have a suggestion? I know that I can replace it with anything I want but was curious if it was possible to get a mixed knot. Thanks for any help.
