His many good 'uns here.
eBay selling of everything. Even broken stuff that is advertised as such and people buy it and love it. Recently found a pile of old chargers. Couldn't even identify them or guarantee they worked. Still, went for a fiver. So satisfying.
Tipping body lotion bottles into jars overnight so I can get the last out of it.
Reusing bathroom bin liners. I just tip the contents into the black bagged bin before i take it out. It's usually only tissues and buds anyway.
Blending honey especially if it's crystallised and DP then reaches for a new one
. If I have a couple of jars standing about I just boil them up and blend them all into one.
Making my own ketchup from tomato purée, dash of honey, olive oil, pepper salt and lemon juice. Lush and I never have bottled just blocking fridge for ages.
Making my own window cleaner out of vinegar water and dash of washing up liquid.
Someone at the start of the thread who cuts off these little pieces of ribbon that hold tops on a hanger. I do that too and keep them as ribbons for small gifts. 
Washing dishcloths until they are really unusable
Making my own scented candles as gifts and to use at home - candle making sets are dirt cheap on eBay
I still use bar of soap for the bathroom sink. I do what my grandma used to do. Always stick the small left over bit on top of new soap so it doesn't go to waste. Thanks Grandma! 👍🏼
Saving old tights as very thin thread for fixing very small tears in clothing effectively. Works a treat!
Loving this thread 👍🏼
