This was designed for artists to easily draw portraits. The 120mm head height is large enough to give ample space on a drawing page for hair and background art. The opposite side has a marking for 1/3 head height and half head height in proportion to the circle.
All you have to do is draw 1 side, mark the center points, reverse the the guide, draw the opposite side and mark the center of that. Then map your face and use the 1/3 marker to draw the chin.
This tool is great for learning, starting sketches more quickly and come with a hole to place on a hook or a key ring.
Great for anime, manga, cartoons, self-portraits and much more.
This is my first upload and I would love to get feedback! Tell me what you think of my design and if it was helpful!
