If you are making your friend a bed jacket...for the hospital...for end of life care *sigh*, I highly recommend you split the sleeves for quick access and iv's. I would split it on the top of the sleeve, from the shoulder to the wrist, with an overlap section secured by bits of velcro that wont touch the skin, she'll be sensitive. overlap section so there is no gaps for her to get chilly.
my most tender affection to you and your friend. :-(
