WarmingTriangle
Just like every year, Christmas is here so fast that there's not enough time to buy a present for all your near and dear ones.
This idea is the solution to your problem and the contemporary replacement for an open fireplace.
Just turn your warning triangle into a warming triangle.
You can do that by equipping it with foils and small light bulbs so that it can fulfill it's new job. Of course you can also adjust the temperature of the warming triangle to your liking:
The more foils you attach to the front, the more cozy and comfy the fire.
So with just a little effort, you can produce a beautiful present your friends are going to love and that costs much less than breaking through the walls for a real fireplace.
