Here’s a simple and free pattern for ear protectors.
My husband has a larger head, so standard face masks are uncomfortable for him. He swears by these and wears them every day!

Very easy to adapt for smaller or larger products by adjusting the base chain.

Suggestion base chain sizes:
Small = 20 chains
Medium = 24 chains (pattern shows this size)
Large = 28 chains

Enjoy!

Happy Crocheting!
