The term hem originally comes from fabric-making and describes material that is doubled up and folded over. Hems can be seen on many items of clothing, such as at the bottom of trouser legs or at the end of t-shirt arms.

The main functions of Hems are:

• Remove or hide edge imperfections: Since Hems fold edges over on themselves, they can be used to effectively remove sharp edges or to conceal cut edges or other defects.
