Not sure if anyone already mentioned adult blanket hoodies but 2 years ago we were all literally freezing in our house. 5-bed open plan rooms for the most part, suspended floor in living room. Office converted from a garage. In 'normal' conditions the rooms feel perfectly fine and comfortable but in Winter it's like living in a freezer. We did put the heating on for short periods to try and 'warm up' the rooms we were using the most (living room, bedrooms, bathroom) but it made no difference. Sometimes my feet and legs were so cold it felt as if I was sitting in freezing water. The cost of trying to heat our home became a real cause for concern.
Not wanting to repeat that experience, last year around end of September, I bought some adult blanket hoodies, seeing it as an investment IF they worked and planning to return them if not. But my goodness, did they work! Talk about toasty. We found it's better to heat the person (the heat moves around with them) rather than try to heat rooms. I got 2 of these garments for each of us - one knee-length and one full length - and they wash really well and dry quickly. We have LIVED in them and rarely need to put the heating on at all now. My daughter and I both like the patterned ones (I have the polar bears in first link) and DH preferred plain so he has light grey - he changes as soon as he gets home and combined with thermal socks and slippers, remains toasty until bedtime. We have 'teddy fleece' bedding with lightweight teddy fleece throws and are snuggly thoughout the night.
For Christmas this year I bought myself a couple of new hoodies from Dunelm. These are just as war but much lighter to wear (not that the others are heavy or uncomfortable in any way), wash and dry quickly, available in several colours and cheaper than the ones from Amazon - some currently on sale too!
As I said, I consider these adult hoodies an investment and we are not worried or concerned about whether we need to put the heating on to get warm. I appreciate not everyone will be able to buy 2 for each person in the household (they have children's size too) but perhaps those who are skilled at sewing could buy single throws made of same material as the Dunelm ones and make your own! I considered that myself and if my hands were less troubled by arthritis I would have made several. I've seen the single 'teddy' throws for as little as £7.99 on Amazon or double at £11.49 - folded in half with a neckline cut out and the sides sewn, they would be perfectly fine.

Amazon Link 2 (extra long, DH)
Amazon Link 3 (teddy fleece throws)

Anyway, thought I would offer this up for anyone who wishes to buy/make their own, and maybe reduce some of the anxiety/stress the heating issue causes many of us. We wouldn't be without ours now...
