This instructable will teach you how to sew your own eye mask. It's a little oversized and has excellent light defeating properties. :D You can fill it with anything you like - my personal favorites are jasmine rice and dried lavender, but this time I am choosing to just line it with felt.
I've included a basic eye mask pattern which you can alter as needed. This eye mask uses very little fabric and just a tiny bit of elastic and is very easy to sew. It's such a small project you can even sew it by hand
! It's also a good candidate for adding some embroidery or razzle dazzle. Whatever you want!
