I know this is not really a how-to, because the only thing you really have to do is acquire a paper towel holder ;)

And no, I don't mean those rolls of cardboard that the paper towels are wrapped around, I mean the things you put that roll on. They usually consist of a wooden rod on a wooden base.

Since these things are hideously impractical (you need both hands to use it! How's that better than just putting your towel roll on the kitchen counter???) and ugly (or they'll get ugly pretty fast if they're made of wood), nearly everyone who has one will try to get rid of it when they move or get new kitchen furniture.

Wall-mounted ones could be used for necklaces as well!
