There are three methods, clamp,sew, and glue. The clamp method has the jewel encased in a molded cup with prongs attached to pierce the fabric. This method is especially effective on heavy weight fabrics like denim. The second method is glue. Various companies make glues specifically for attaching jewels to fabric that are waterproof. Others are heat applied, check manufacturer's directions. The third method requires that the jewel have holes. You must sew individual jewels TO the fabric by hand. This method is tedious and time consuming which is why hand beaded dresses are so fabulously expensive.
Bobby pins are typically made of metal, with iron being a common component. When exposed to moisture or high humidity, the iron in bobby pins can oxidize and form rust. This is why bobby pins can rust if not stored properly or exposed to wet conditions.
One method to separate pins and buttons is to use a magnet. The pins, typically made of metal, will be attracted to the magnet and can be easily separated from the buttons. Another method is to manually pick out the pins from the buttons, using tweezers or a similar tool.

With bobby pins.
Bobby pins are great for thick to medium hair. They will fall right out of thin hair. You use bobby pins by just taking a piece of good sized hair and slipping in the bobby pin. The style today is to take a bit of hair from the front and to pull it back. Then you slip in the bobby pink in the middle of your hair line. :)
