These types
of crimps are used to attach a fastener at the end of your work. They give a professional look to the finish of your work. They can also be an easy way to attach several strands of beads to your fastener. An increasing supply of these crimps in a variety of colours and finishes can be found at ClearlyChosen's bead tips and calottes which will give you the super top quality you need..
Even though most of these terms are used interchangeably, the purist will say that there is a distinction between a calotte crimp vs. a clamshell crimp.
Most people would not make a lot of distinction between these variations as far as their names are concerned but how you would use them in finishing your work is a bit different.
Calotte crimp
- is side-opening with no holes.
(See a simple way to finish with calottes.)
