The seam that must be undone gives precision another chance before it becomes permanent.

Unpicking is not failure but the moment at which correction is still cheap. A seam undone now costs twenty minutes, while the same fault left in can cost the garment. Willingness to go backwards is what makes accuracy possible, though it always feels like ground lost. Most crafts rest on the ability to reverse a step without shame.

Look at something you are working on where you already know one part is not right. Take it out now rather than building over it. And count the undoing as part of the making rather than a penalty for having got it wrong.
