It's getting chilly

Although the weather has been lovely in the daytime so far, nights are starting to get chilly.

I live in an old house opposite a wood. When I sit on my sofa and look out of the window all I see is trees, bushes and a path leading into the wood.

So this is what I see when I'm siting on my sofa

This picture was taken last Spring. It always sets off with the small trees and bushes, and gradually all the other trees follow. And it's such a thrill after looking at bare trees all Winter.  Winters always last far too long, and I hate them with a passion.

But bare trees aren't the only reason I hate winters. The house has central heating, but only the living room is relatively warm during winters, not the bedrooms upstairs. Which is unfortunate, because my sewing room is upstairs, and so is my bedroom.
Anyway, last winter I consulted the housing company about it. Turns out that the HR-boiler is set up to heat bedrooms to 15 degrees Celsius max. Apparently you can request to change that, but then I would have to worry about my energy bill. So that's not an option.

To make matters worse, we have those ventilation things (I don't know what to call them) in the windows. Well, the thing is I have to leave them open at all times. If I don't the air gets too humid, which results in an even chillier feel in whatever room you're in.
So I leave the vents open all the time, meaning I feel the wind blow over my face when I'm in bed. And with temperatures below zero that's no fun.

So I'm thinking about a quilt to put on top of my bedding for extra warmth, since my bedroom is so draughty. But will I just buy one from Ikea or make one?

At the moment it's more likely that I'm getting a bedspread/quilt from Ikea. It would serve its purpose this winter, and give me more time to make myself a nice quilt.

After all, there's the size to consider. My bed is 47.25" wide and I want a decent overlap to keep warm and for appearance.   Well now, a quilt top goes together fairly quickly, but after that you still need to quilt it. And I'm a hand quilter.
Of course I could try to machine quilt it, I suppose. Yet,  that would mean handling a sizable quilt on a domestic sewing machine.  Would that actually save time?
Still, it's tempting, I must say.
