When you start drawing most people draw flat on a table but if you can access an easel then I would recommend using one. Some learners feel quite intimidated by the easel, with all its screws and parts they seem cumbersome and unnecessary. It might be worth giving it a try and seeing how you get on because drawing or painting on an easel is quite a different experience to drawing flat.
Give the Easel a Chance
At first it will seem a bit strange to anyone who is used to working flat on a desk or table because you are standing up usually instead of sitting. The other thing that feels very different is the angle of the paper, it is upright on an easel rather than flat.
