Bob, I was actually thinking about cutting it in half, and starting from there so I didnt have a 6 inch or so handle, but i would love to have a gigantic brush. Why not, at least it would be different, just have to let the imagination run wild. Thats whats so great about this site, the fact that nobody has said it couldnt be done. Just giving alternative ways to get it done, its incredible. Now back to your thought about a larger knot, where is a good place to find said knot larger then 25mm?
