When I travelled for w*rk I always took the extra roll of TP in the room....and I too grab handfulls of napkins and save them....
I save even small portions of leftovers for lunch the next day. Once I realized that frozen dinners have so little quantity in them for the amount you pay, I stopped tossing perfectly good small amounts of leftovers.
I cut up old kitchen towels into 5" squares and use one under my multiple cups of coffee in the morning, in place of paper napkins to catch drips. When I return to the kitchen for more coffee, I rinse it out and reuse it, then they go in with the rest of the wash....
I live alone, and in the winter I hang all clothes up to dry on the doorframes....releases moisture into the air as well..they dry super fast so you can imagine how dry the air is....I also dry all socks on my one cast-iron radiator.
I make orange juice from concentrate....after I discovered a LOT of the name brand juice is just that, but they charge three times as much!!! I like a half glass first thing to get that sugar jolt......
I have two cats...use the foil lined bags from thier dry food for collecting their waste. Don't leak or release smells. ALso found that Aldi's clumping litter is a fraction of what the other brands/stores charge and works as well.
I try things at Aldi before I make a judgement. In the years I've shopped there, I did not like their jarred red cabbage or liquid dish soap, otherwise I save a small fortune shopping there.
DOuble bag my groceries with store plastic bags, then use them for garbage each day. End of day that small bag gets tied off and placed in one large g-bag for later collection. Only need one large plastic bag a week!!!
The usual.. hang clothes on the line to dry, wash my own car (except in freezing winter-then run it thru the wash once a month....it pays to keep up with keeping it clean..
Yes I am cheap but I don't care!
