Plaster washers are great ... but I never seem to have a stash of them handy when I need them, and nobody in our neck of the woods carries them (or, at least, nobody I know of).
So I use what is at hand.
Typically in the past when I've need plaster washers, I've grabbed a piece of aluminum roof flashing and then cut pieces of it into inch or inch-and-a-half circles -- then attached it to the wall using drywall screws to re-key plaster. This works fine.
Currently we Holmeses are reworking the kitchen in our 1878 Victorian house. The other day I needed plaster washers. As is always the case, I didn't have any.
This time, Deb took one of the stiff clear plastic semi-throwaway freezer containers - one of the ones made by Glad, or Tupperware, or similar companies - and cut up a bunch of round pieces. And then I used them as plaster washers. They worked great ... pulled the plaster in nice and snug to the wall ... and drywall mud sticks nicely to their surface.
So there -- for anyone to poke holes at, if they wish -- I've given away one of my "tricks of the trade."
