How Much Trim Do I Need? Measure Yardage Correctly
Measure each line where the trim will actually sit, multiply repeated pieces, and add the results in one unit.
A good trim plan records the actual sewing path, the number of pieces, and what happens at every join or turn. The shop-cut length is the ending of the calculation, not the opening guess. These guides favor flexible tapes, labeled samples, and arithmetic that can survive contact with a real cushion, collar, hem, or lampshade.
