which knee do you propose on

The tradition is to propose on the left knee. This custom comes from medieval times when knights would kneel on their left knee as a gesture of respect, keeping their dominant right hand free to hold a sword or open the ring box smoothly during a proposal. The left knee is also preferred for visual appeal in photographs, framing the moment nicely. However, the choice of which knee to use is ultimately personal, and the sentiment behind the gesture matters more than the specific knee. Most experts agree that the "right" knee is the one that feels comfortable and sincere for the proposer.
