She was wearing a black wool sweater whose long sleeves covered until half of her palm.

I'm trying to describe a situation when sleeves cover half of hand. Is "cover" correct?

Is this okay?

Remove 'until', and it would be okay. I'd probably also pluralize 'palm'.

I think I have seen things like 'palm-length sleeves', as well.
