How To Draw Igloo. Once you've built your igloo, cut out an entrance way and fill in any. Begin by drawing a curved line, like a semicircle, to outline the top of the igloo.
Draw a black hole in the smaller shape. Start the door with another upside down curve. Once you've cut out all the blocks, stack them around the perimeter of your circle, gradually sloping the blocks more and more each time you move up a layer.
