Old fashioned bed warmer

Okay bring on the next overnight stay I been and bought myself a real old fashioned copper bedwarmer.  I will be putting my firebrick inside it (with all fo' corners knocked off) and possibly making it a little coat as well so I don't burn myself as I will be sleeping with it!  In the summer it can be a wall decoration.

Only £20 from a junk shop (the sort where all the antiques are just piled on top of each other and there is absolutely no room to walk about).  He had several and we managed to access all of them without the whole room tumbling about our ears.  I chose the one most likely to fit said brick.
