Start with extra leather and thread. Cutting off excess is better than running out too soon!
Follow the blog instructions to properly secure your thread at the start of the project.
To make an adjustable bracelet, tie a 3rd knot at the end of your leather. This will create a second loop for the button to go through.
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.
