My carry bag holds; Camera, few paper towels, small water container, value scale, pencil, white eraser, palette, paper, brushes #8 round/3/4 flat/ rigger/fan/baby tooth brush/ and a folding chair that fits between handles.
No need to haul a cumbersome easel, sit in chair, paint on lap, palette and water on the ground. Easy!
In my week long workshop in September, I will suggest bringing an easel.
