Draw a horizon line across the page
Place a single vanishing point on the horizon line
Draw the front face of the object or scene
Connect the corners of the front face to the vanishing point with straight lines
Use those lines to guide the depth of the object
Draw the back edges parallel to the front edges where needed
Erase extra construction lines
Add details, windows, doors, or other elements following the same perspective lines
Keep all receding lines aimed at the same vanishing point
Check proportions and alignment before finishing
