I am making a mug in blender based on a picture. I make the make in Front Ortho and it's just fine but when I look at it from different angles it looks completely wrong. Why is this happening?
This often happens when you extrude with CTRL + LMB🖱. It's better to model objects like that bevelling a curve and combining them with CTRL+J later. Bevelling a curve lets you shape the object any way you want changing the curve as long as it is in 2D mode. And the handle is not choppy then.
