After much removal and filing and destroying, it turns out there is a huge surface to work on top of my plan chest.
Here's a little selection of my much loved tools. Third from the top is one of my old time favourite pencils. It is at least 20 years old, and you can no longer buy something this well made anywhere. Some were made in countries that no longer exist, but they still work! Ah the beauty of a well crafted useful object! Bottom ones are a more recent discovery, artist quality wax crayons. Grainy, flowy, really vibrant, a delight over acrylic.
