I made the two drawers surface sticking out and denting in at a balance that I could pull out the drawer easily while it is still hard to fall into the easel case when I carry it around.

The seperate structure of the easel board (also as the case lid) and the case body is due to the limit of the cardboard sheet (which is 60''x80'' at most). But this way the easel board is cut in vertical grids so it is more stable while performance. It also creates the shelf space to keep the drawing pad in place.

The grids inside help secure the drawers in place and prevent them from going further into the easel case. The dents on the grids are used for keeping the supporting board in place from being affected when the drawers are moving.

The tilted degree of the easel case body is intended for the extra space taken for the portfolio folder attached to the supporting board, so that it could be easy to close the case seamlessly.

The cardboard case is assembled by tabs and the body of the easel case is made continuously on one sheet of cardboard.
