Cut the leather at an angle to assist in fitting two ends through the hole of the cross connector. For a better grip on the end of the leather, consider using serrated flat-nose pliers to pull the leather through the hole.
Loop the leather ends through to make a lark's-head knot.
String the beads onto the leather cord.
For added strength, add a dab of Bead Fix to the leather ends before crimping. Crimp by squeezing the center of the crimp firmly with round-nose or narrow chain-nose pliers.
One or more parts (or tools) used in this project are no longer available, so we've moved the whole project into the "Misc Jewelry Tutorials with Issues" area while we decide what we want to do about it: find a good sub, re-make this project, or retire the tutorial.
