What a great friend you are! I am part of a nonprofit that gives gift bags to chemo patients on their first day of chemo in the hospital and we always include a blanket or fleece or afghan of some kind (like to do hand made when we have them, but usually store bought). Some (I think most) of the chemo drugs make people get cold. I know I have ALWAYS "run hot" and when I was in chemo last year, even during the summer months, I always was under a blanket in the lab.
