At Casa RoboShark, we like a nice crisp bed to sleep in at night. My mom showed me a few tricks when I was younger, and they are sticking with me to this day.
What tricks you say?
Well… get your favourite sheet set and follow me, I will demonstrate:
First, lay down the fitted sheet and tuck in the corners tightly:

Then take the flat sheet and spread evenly and tightly to match the head of the mattress with the design facing inward… Don’t question me, you’ll see why shortly:

In Winter we add more layers, so let’s add the duvet. Spread it evenly but leave at least 6 inches at the top head of the bed:

And then rigth after that, we add the really warm faux-fur blanket, same as duvet, spread evenly leaving 6 inches at the head of the mattress. Your duvet and blanket should lay evenly, with the flat sheet sticking out 6 inches:

That is when you take the extra 6 inches from the flat sheet and roll it up once over the duvet and blanket – and – then all 3 layers are rolled up once more, giving this effect:

Now you understand why the flat sheet was facing down. Don’t you feel like a loser for questioning me? I forgive you.
It’s time to add the pillow shams, resting against the manly headboard:

Quickly followed by the pillows which we put right against the shams in the exact same position, nicely filling up the empty space left when the flat sheet was rolled onto the duvet and blanket:

Sweet isn’t it?
Now comes the free form portion of the programme, this is when you can be as creative as you want… For our Winter bed, I go with manly over-stitched suede cushions and a nice woolly southwest design with matching colours:

You don’t have to stop there, add more… I find sharks, polar bears, monkeys and monsters can add that final “We’re 45 yr old Men” touch. Also should you need it, you can always add an animal print smaller blanket at the foot of the bed, it’s a really nice touch on very cold night, your feet will thank you:

And there you have it… our bed… in Winter!
Oh sorry, one last addition:
