I recommend painting the whitish surface first, and cover the entire canvas with the paint (tint the white paint with burnt umber, sienna, or whatever). This makes the job easier. After it has dried, you could draw a fine line with charcoal, which is what artists often use. You could use a piece of cardboard and paint along it to get a straight line. There are many methods, of course. The standard method, when painting rectangular shapes or lines, is to use masking tape.
You should probably make a study first. That's what I always do. Malevich used to make studies with a lead pencil on paper. For studies, it is ideal to use crayons.
