When a loved one faces a huge medical challenge, to make them a small, personal quilt is a great gesture. It's a lasting hug and a reminder just how special they are to you. How they chose to use it, be it at home for comfort, or to take along to treatments leave to their own option. It's important that whatever you chose for fabric and color, you just keep in mind what the recipient would love. Later, they can look at the quilt, still enjoy it and remember the comfort it gave them through tough times, but not necessarily represent the "disease". Just my opinion.
