Guide to bringing a silk topper to a high polish. Mostly based on self-experimentation and some existing practices.
NB: I’ve taken this article off-line because I think you really need to know what you’re doing before attempting to tallow polish a topper and also because I now believe the water polishing method isn’t really good for the hat so don’t want to mislead people into using it. Therefore, I would only advise using the brush and velvet pad for polishing whilst leaving actual tallow polishing to the professionals.
Not a guide but an explanation of how silk top hats are made. With links to videos.
