WHEN I SAVED THE PRUNED TWIGS from my pear and apple trees for smoking material for barbequeing, I had no idea that charcoal sticks suitable for drawing would result. The twigs were from last year’s prunings; soaked in water and then placed in a cast iron smoke box and placed over a gas burner in the bbq to flavor whatever it was we barbequed. When the smoking was done, these hard little charcoal sticks were left. They sure resembled vine charcoal, so what the heck-I tried one and saved the lot! I love this kind of surprise discovery. Maybe I’ll use it to sketch some pears and apples!
