I live alone so sometimes have a difficult time putting a bracelet or watch on by myself so I tape one end on my wrist with cellophane tape so it stays put and then I can take the other end and hook it together. Works every time!
Wearing a bracelet with a clasp takes time to put on. It can make you angry sometimes or even fall off when it is already on your wrist! I just cut a small piece of Scotch tape, put my bracelet on my wrist and tape it on. That way, I can hook the clasp on the ring of my bracelet without it falling off my wrist.
Bracelets and necklace clasps come in myriad of shapes and styles. This is a page about fastening a bracelet.
