Consistency beats precision. Cut to fit, not to a number.
The most common beginner mistake is chasing the number on the plan instead of the fit in front of you. Parts that should match need to match each other — whether or not they match the drawing.

The short version #
- Consistency over precision — if matching parts are the same length, the project works even when that length is slightly off the plan.
- The exception is joinery — a tenon in a mortise has to fit exactly. Spend your precision where parts connect.
- Cut to fit, not to a number — use one part to mark the next, or cut them together.
- Use a story stick — transfer key dimensions from a piece of scrap instead of re-reading the tape every time.
