I have a pattern by one of the major sewing pattern companies. I think it was simplicity. I hope she realizes heavy items could make her unstable if placed un balanced into the pockets. Just trying to be smart here.
Maybe you could ask her what type of items she plans on caring around with her and custom the pockets for her. Another item that might be a nice gift would be to make her an organizer pocket that hangs on the wall near where she spends most of her time. Or perhaps a chair pocket organizer for her lazyboy arms.
