It's does kind of ressemble eyelash yarn but they're calling it boa on the packaging so I wouldnt say it is eyelash. It has a different texture than the last eyelash I worked with also. But similar .
I've used this yarn and i love it- it's feathery to the touch and pretty easy to work with once you get used to it- i have made skinny scarves with it, as well as a shawl for my niece.
