These old alumnium foil trays have loitered too long on the top shelf of my kitchen cupboard. I harboured good intentions of reusing them, but never did, and probably never will. I held on to them out of guilt for buying cheap disposables in the first place. Fortunately our council recycles foil so they're in the black bin waiting for Friday's collection and I won't be buying any more.
So far so good. Working through cupboards and drawers I've had no difficulty finding items I can happily part with. It's as if this challenge has given me permission to dump stuff I've been wanting to get rid of for years but never felt confident enough to do so.
You should try it.
