Cape Breton bracelet - tension clasp.  For a proper fit, it is best to take a wire or cord  and loosely measure around your wrist where it will be worn. Then open the wire and measure the length in inches or centimeters. I will make the bracelet to that measurement.  

       The bracelet should be put on sideways and then clasped, ( not over the hand ) .  There should always be a bit of tension where it connects. If the tension becomes relaxed, simply and gently pull the connecting catch  outward enough to re-establish  the tension.
