Now to root out some ugly linen napkins we got as a wedding present and make some decent char cloth.
Any advice on impregnatong the finished article with the KN03? , strenght of solution and such?

Charcloth does not need to be dipped in potassium nitrate. It will catch a spark without that. But if you dip/soak cotton/linen cloth or cord in potassium nitrate, you will be making "slowmatch" - what would have been used in a matchlock gun. You strike a spark on the end of your Slowmatch, and then it continues to slowly smolder without just going out. In use, you blew the ash away from the end, and the pulled the trigger to lower that glowing/burning end into a small amount of black powder in the pan on the outside of your matchlock gun. That touched off that powder, and the "flame" then blew through a small hole in the side of the gun barrel, and then it ignited the powder inside the barrel to shoot the gun.
But if you want to make amadou, then you do need to soak it in potassium nitrate. You cut out that thin/fluffy layer from a shelf or hoof fungus (between the hard outside layer and the Gills inside). Then pound that layer a bit to "fluff" it up some more, and then soak in your water and potassium nitrate solution. After it has soaked a while and become thoroughly saturated, pull it out to drip and dry out. The stronger the potassium nitrate solution, the faster it will burn when it catches a spark. But once your new "amadou" is made, it will catch that spark fairly fast, and then be pretty hard to put back out. It will spark and fizzle much like a firecracker fuse, but not burn so fast.
How much? When your water will no longer absorb any more potassium nitrate. You will start to see undissolved crystals in the bottom. And if you let the water evaporate out of any left over solution, you will be back to having just potassium nitrate (possibly with a little calcium in it from hard water).
If you do a search for "slowmatch" or for "matchlock", you should find several web sites telling you how to make that slowmatch. How much potassium nitrate you get into it will affect how fast it burns - either slow smolder or fast like a firecracker fuse.
Hope this helps. Be careful with your playing.

p.s. Thanks for the info on that Byant and May collection. I figured it still existed somewhere.
