The quilt is absolutely gorgeous! I'm sure she will feel wrapped in love! As a two time breast cancer survivor myself, I know chemotherapy can be very grueling. You get hot and cold flashes constantly from all the steroids they give you to avoid allergic reactions. But I was always cold during chemo treatments and constantly needed a blanket during the IV's. Many of us brought our own quilts from home instead of those ugly white sterile looking blankets that the cancer center has.
Having been through that twice, I can promise you, it's the little things people do for you when your sick that make you feel so loved!! It was quite thoughtful of you to do that for her!! I'll keep your sister and your family in my prayers!!
