Hello to all of the talented sewers out there. I'm hoping you might share a word or two of advice about how much of a job it might be to have the sleeves of a blazer re-lined.

I was thrift shopping this afternoon -- thinking I might try a men's blazer to play around with truly oversized in a low risk way. I found a nice navy blazer that would have come home with me except that the lining of the sleeves was badly stained and coming unsewn at the cuffs.

How feasible might it be to have the sleeves relined? TIA for any insight you can offer!
