A safety pin is a device most commonly used to attach two pieces of fabric together. The safety pin was invented in July of 1849 by Walter Hunt . The rights to the invention were sold for $400.

Made of rigid but bendable material, it is activated by squeezing the parallel sides inwards. It is safe because the sharp needle tip is covered when the safety pin is closed. It is used for clothing and other cloth that has no special provision for attaching such as buttons or a zipper, and for provisional repair in the case of some imperfections of clothing. The safety pin is useful in sewing but earned its fame in punk rock attire, where it was used to pierce skin or clothing.

The safety pin pierces and goes through the surface of the material with its sharp end then joins back up to a shielded end on itself holding the object in place. The safety pin is strong, safe and very durable. The downside of a safety pin is that it is easy to spot on a dress if you are modelling and small children can swallow it if it is left lying around or comes off their nappy.

Safetypins are very common and inexpensive. You can find them almost everywhere.
