I am going to change to real soap (and indulge myself with nice scents from l’Occitane ) when the current shower gel and hand wash give out. I understand that keeping unused bars in a chest of drawers not only makes things smell nice, but discourages moths.
As mentioned on another thread, changing to leaf tea instead of teabags is another small change, but I think a good and useful one.
Tinfoil or butter papers instead of cling film in the fridge, an upturned saucer/plate over a dish in the microwave?
Butter in packets instead of tubs of spreadable butter, a reusable water bottle and coffee cup.
Just a few things, but surely al helpful.
