Apologies for the awful threadomancy, but this is such a great idea - and insanely effective - that it should come back even if it was nearly three years ago. There's almost no setting I can think of where I wouldn't use these - barbarians raiding an sinister temple, chain-clad armies battling over fields where ancestral monuments mark ancient oaths, Dwarven heroes defending their halls from waves of Goblins, mustachioed adventurers braving the darkness of no human aspect, far-future super-warriors hunting aliens and heretics among the crumbling ruins of the Empire of Man... everywhere has pillars!
I, too, have some corks. Not a big bag of plastic ones, I have the other sort, the expensive ones you get one at a time. Often, though, you get a free bottle of wine with them, which is some compensation.
I will be making some pillars with them. Having seen people using corks in a couple of places, with slightly different takes on the capitals and bases, these are my favourite, and it's the use of the bases for capitals I think that set them off.
So, I have ordered some bases, and I hope soon will be showing off my own (not doubt sadly inferior!) copies of these lovely pieces.
