What you need
Fine Clear Elastic Cord
This project is almost too easy, but it does look great especially with a lot of the bohemia styles coming in to fashion.
I wore one of these using a zirconia bead which looked stunning and simple.
Start by threading the bead onto the elastic, measure it around your finger and mark the elastic with a marker.
Then take it off your finger and tie the knot as close to the marked line as possible.
Snip the excess thread off.
