Challenges I see:
Prepping fabric - washing, folding, ironing, starching. 1. Cutting the fabric into smaller pieces simplifies this part. Ironing can be easier if you turn the board around so she works on straight sides.
Cutting fabric - scissors or rotary cutter, 2. You can offer to trade a skill she still has for doing her fabric cuttiig.
Matching seams - How can this be managed? 3. Binder clips can be used instead.
Pinning - I could not manage this one handed.
Sewing - is her machine an old one where you have to nudge the flywheel to get started?
Quilt sandwich
Quilting - this could be possible if she has a LAM and someone loads the quilt for her or she quilts by cheque.

Perhaps there are other ways she can participate in quilting, if she wants too.
