Love your quilt. With borders, I think the size is pretty good. If you are going to do a scrappy outer border I would suggest a plain white inner border. I have made a number of what i call comfort quilts for people battling cancer. The need to be large enough to be useful and small enough to be easily taken along. Everyone I know who has had chemo says the process makes them cold whether it is the temperature of the room or of the the liquid being put into their bodies. I am sure your cousin will appreciate this quilt very much.
