I have been crocheting headbands and a friend of mine wants me to crochet him this face mask? that covers just your nose and mouth. I asked him what it's called and he said it was a theil? or something like that, I'm not really sure. I've been trying to find out how to make it and I've searched youtube for how to make it, but have had no luck. Can anyone tell me what it's called and/or where I could learn how to make it?

It is likely some variation of a bacalava
