Kilts for the forge

[DragonsTooth]

I am looking for a bit of help. I want to buy a cheap wool (or something a little more spark resistant) for use at the forge when im forging blades at my anvil. I've seen all the poly-blend ones and am not keen to go up in flames. I am also not a fan of the Utilikilts at all.

What other fabrics can be used to create a lightweight and safe kilt and how much (GBP) might I expect to pay for one - preferably in the (modern) Gordon tartan?

Any assistance would be greatly received

(I would also very likely wear a leather apron too but i just wat to see what the consensus is)
