Wherever two pieces of fabric are joined, in addition to a single pass on the front face, The King also makes at least two passes on the reverse. The seams on a bookbag from The King simply don't tear loose, no matter how long the bag has been in use.
例如在布與布的接合處，除了會在正面先車一條外，反折過來至少還會再加車兩條，就算長久使用，縫線也不致鬆脫掉落。
