I've got greens, greys, a little black and some beautiful chestnut colours. To be honest it could be a really interesting finish - distressed / weathered... but it's not what I am after (and I'm not sure how consistently it would develop). I think the india ink might be the best route. Will have a go later next week - thanks for the tip about the timbermate. Can you just spray nitro straight on the inked wood after leaving it dry for a long enough time - or is any other prep needed. ?
