Your design 7431, Bangles with Swarovski Pendants has some kind of base with holes. What is it and what kind of beading wire is used to string the crystals on the bracelet?
Swarovski provided us with illustrations on how to assemble the project, as well as an illustration of the tool that made holes in a piece of acrylic tubing.
The tool used is a revolving punch, the tubing is for plumbing, both can be found in your local hardware store. Please note, the tubing is available in multiple diameters, I liked the 1/4 inch outside diameter and the 3/8 inch outside diameter as their dimensions work well with the pendants.
The pendants were strung through the holes in the tubing made by the punch with thread; I would recommend Nymo® size D Nymo is nylon based and a very strong thread, size D is the heaviest diameter available.
