 * VELCRO**

it is a type of lettrer. it is make in colors. typically, two lineal fabric strips which are attached to the opposing surfaces to be fastened. The first Velcro sample was made of cotton, which proved impracticaland was replaced by Nylon and polyester.

additionaly, in the United States Air Force, where Velcro is used to attach patches to flight suits, aircrew have learned that they can remove small cloth pile balls that accumulate on the suits by using the hook side on the back of the patches like a brush to remove them.

Velcro has several deficiencies: it tends to accumulate hair, dust, and fur in its hooks after a few months of regular use. Velcro often becomes attached to articles of clothing, especially loosely woven iteams like sweaters.
