The hardest part of a glove is the thumb.
But we won't start drawing with it — instead, with the other four fingers. Since the glove is warm, they're quite chubby. Three are almost the same length, the middle one a bit longer, and one is small — the pinky.
Next, let's draw the thumb. To do this, draw a line down from the index finger about a third of its length, and from that point draw the thumb. It didn't work out for me on the first try, but after a bit of practice I figured out where it should end.
So the glove doesn't slip off, there's elastic at the bottom.
