I have made some curtain liners with other curtains. Should be as warm as bought liners.
You are clever. I am hopeless at needlework, my mother tried to teach me but I disappointed her
I am keeping an eye on what we use both with elec and gas. Elec bills have gone down (govt subsidy) but gas want to put up our DD to FOUR TIMES what it used to be, despite us using only 5/8 of the gas compared to this time last year. Ironically when I went to check our account yesterday they themselves said we were paying too much, and suggested £20 less, to £150 a month which seems huge considering we are hardly using any gas at all, only for a once a day hour of hot water (which lasts two showers and any washing up, though we don't do much as have a dishwasher.)
Helen called up the elec. people to ask for her DD to come down from what they have put it up to, as like us she is in credit by about £200. They replied that their policy is that customers must be two months in advance credit at all times.

when did this come in?!
We haven't needed the heating on much so far, but Mr M feels the cold so I bought two ceramic fan electric heaters for £44 each from amazon, and he puts them on for a burst when he feels cold. He doesn't keep it on long so I'm thinking they will be reasonably economical (more so than having the central heating on) .
Also I bought a new calor gas heater (£144) for downstairs where the rooms are big with wooden floors and a little ceramic heater would go nowhere. As I think I posted elsewhere, they come with no calor gas cylinder and if you don't have an empty one to trade there are none left in the country. We had a half-used one which we've attached to the new heater.
They are very efficient and very cheap to run (£35.99 a cylinder, which lasts months and months) but you have to be careful of CO poisoning so I've had to order a proper CO monitor (not the strips) from ASDA, which didn't come! Will order another asap from Amazon.
