My sketches in this post describe only forms that chess pieces will form.
For example, if I will use stones as a material, I will draw these forms on the stone. In addition, if I am going to shape the cookie dough, I will choose the most appropriate form in here for easy shape.

Also, there is a hierarchy among all chess pieces. I definitely describe it in my own chess set.

I think the most characteristic part of the chessboard is the square shape. I will not change the square shape for this reason, but I am thinking to show the length difference between squares.

I am thinking of drawing squares with a black pen or paint on a piece of fabric. I found a quick way of making a chessboard and also, I can use this method.
