The first step is to cut your macrame to double the length you’d like for your keyring. My final keyring is 10cm long, so I cut a 20cm piece of thread.
If you use beads with a large enough hole in the middle, you can skip this step! Alternatively, you can use a different type of thread that is slightly thinner, such as DK yarn.
When all your beads are threaded on, tie a knot at the bottom. Make sure the knot is large enough so that the hole in the bottom bead can’t pass over it.
