I would try to go to her house if at all possible. I started quilting when I had an illness and couldn't leave my home for any length of time. Not only did it give me something to do, but it helped me heal faster because I became so passionate about it. I don't think I would have gotten out of the house as soon as I did had it not been for this hobby. If it's not too much trouble for you to go to her house, you may find that you help her become more mobile. Her lessons could be life changing.
