Garnierring from a PET bottle
An empty PET bottle can be used to make a garnishing ring in just a few minutes.
If someone urgently needs a Garnierring for arranging food, but has none at hand, you can cut out of an empty PET bottle, which has previously been cleaned, the middle.
I made this with a craft knife and then carefully trimmed the curves with scissors. I can now wash the plastic part over and over again.
