@keisuke 1. Begin by drawing a vertical line from the top to the bottom of your page with a short straight line near the halfway point that divides it in two.

Now draw two small horizontal lines on either side of the vertical line, one near the top and one near the bottom, making sure to keep the beginning and endpoints of the lines exactly on the vertical line.
At the top and bottom of the vertical line, add an arc starting from the endpoint of the small horizontal lines, which should create the “H” shape.
