Keeping Warm in Winter without breaking the bank - What do you do?

They look lovely, but I can't see myself managing to squeeze my rather prodigious Buddha Belly into those. If I could, and I did and then tried to sit down, I strongly suspect I'd do myself a mischief. I stick to my granny pursuits of knitting and this pattern is my favourite for bedsocks. I've even made quite a few pairs (pattern modified for size) for my hubby who has size 12 feet. I tell him he doesn't have feet....he has yards...
