Why Seam allowances and shrinkage to be added to the patterns? 

In the event of a washed piece of clothing, 100% fabric ought to be tested for shrinkage. The test is done according to the wash formula. When all rolls are tested, the rolls are isolated according to the shrinkages and various patterns are made to fuse the shrinkages.

If there should be an occurrence of a non-wash piece of clothing testing 10% of the fabric is adequate to decide the shrinkage that should be incorporated into the pattern. The pattern is washed in view of the suggested wash care directions in the FPT.
