There are several mask ear savers out there. Some you can customize, others you can’t. This design lets you create an ear saver you can adjust.
It gives you a very simple, easy, and quick project to make. You can attach it different ways and are able to adjust it tighter or looser. This ear saver is done in 3 easy rows, and then you just sew on a button.

This project uses a very small amount of yarn (just a few yards) so it will be good to use up those scraps you have. I used worsted weight cotton yarn for mine but you can use any yarn you’d like as long as the length comes out to approximately the same and you use a button that will fit through the openings.
