Use paper and a ruler to create a template for evenly spacing the first holes for the rhinestone chain lengths.
Poke awl through the template and leather cuff, into scrap cardboard.
Cut first length of rhinestone chain approx. 5.25", then use this length to measure subsequent pieces.
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.
