Thank you for all of the thoughts. I do know that elderly people can tend to be cold - my 92 year old mother-in-law is always freezing and my sister-in-law has to keep the heat cranked up. I don't know about my aunt, but both she and one of my cousins told me that she is really in pretty good shape - no major health issues, other than some neuropathy in her feet that makes them numb, but she said they're not painful. She's also still very active in her church and is always on the go.
In fact, she just went out and ordered herself a brand new SUV! My cousin told me that she wanted a red one, but she ended up ordering a metallic blue one instead. She said she got tired of driving my uncle's old pick-up truck (he died 10 years ago.) Ya just gotta love a woman like that!
I have a question for those of you who have used both QD wool and the Select cotton batting - are the cotton quilts significantly heavier than the ones made with wool? I think I need to call one of my cousins and ask her some things - I want this to be a surprise for my aunt, so I don't want to ask her.
