How to tie the two elastic bands of a face mask together with one rubber band? After buying some new face masks I have found out that their behind-the-ears bands are way too short and are hurting my ears. I have decided to try to "bridge" them behind my head, and the only material that seems useful for this purpose that I currently have access to is a bunch of rubber bands.

I have managed to tie a rubber band around one of the mask bands, but when I repeat the same procedure on the other band it just comes undone. Honestly, it's breaking my mind a little.

When using one rubber band for each mask band, I can tie them together with a simple knot and it works, but there must be a way to do this more elegantly.
