Or... C could be for... Charcoal!

Or... C could be for... #Charcoal!
I'm trying to think of a few alternatives for some letters - moving from flora and fauna to some other things that might be found in the woodland - some with more of a human influence.

So - here is some charcoal, made in the woods, from wood (in a tin, not from the wood). 

I realise I should have drawn this in charcoal too really- I have plans to mix up the sketchbook a bit in June and dig out other mediums that have been dormant for months!
