I got tired of my nice chiseled brights (brushes) getting frayed and ragged around the edges. when i paint i like a nice chiseled edge on my brushes so i started doing what i used to do back in my old sign painting days. i started wrapping them in between painting sessions, and now they stay sharp waaaaayyyyy longer. here's how to do it.
By the way..... this will work with any brush- synthetic or bristle
wrap it around once and push to make a nice chiseled shape out of the bristles. the tape sticking to itself and the bristles will hold the form
then wrap it around once more and there you go. the things keep their shape forever now. Give it a try!
