Rag rug earthing mat.
I am a huge advocate for earthing/grounding. Living in a city walking bare foot is not ideal.
You gotta get those electrons, so after Freya chewed up my earthing mat I decided to make my own.
I wove copper wire into a rag rug as I made it, which you then plug into the earth socket. Thanks Tristram for sorting that bit out.
Its even more magic as there are written spells hidden in there too.
