This is where it all happens, far from drawing studios of old, not a piece of paper in sight, crazy. I use a wacom utuos 3 ( I think ) drawing tablet with A4 drawing size area, present from my wife about 5 years ago, second hand ones go for about 200 now, perfect for my needs and more probably,  takes some getting us to. I have an A4 drawing pad, for doodling rough sketches out on and try to carry a small note book to jot down any ideas that I have.
