Oops!
There's nothing more disheartening than coming to the end of a project and realizing a mistake.  Today I was changing the clasp on a necklace given as a gift when I crimped the last crimp bead only to discover that the necklace was too loose.  Too much wire was left over.  How do you fix this when you don't want to restring?  Crimp covers!  I simply added two to the back of the design and fixed the problem in a fraction of the time restringing would have taken!  Phew!
