I read some threads on restoring brushes with new badger knots and found TGN and now I really wanna try restoring a couple of old brushes that I already have. Is there a primer here or elsewhere on how to? how do you determine size? can you replace boar or synthetic with badger? (OMG! my wife thought I was cured of the ebay bug. the world is now again filled with possibilities! she's gonna kill me 
)
