One-Handed Punch Needle?

Hey, slightly weird question. My family does a themed gift exchange for Christmas every year and this year the theme is arts and crafts. I love fiber arts so I would love to get a little fiber arts kit, but the difficulty is that I would want it to be accessible for my grandmother who is partially paralyzed and only has the use of one arm/hand. I thought of punch needle but I've never done it myself.

Any ideas of how hardit would be to do punch needle with one hand? She does the diamond art kits, so she can do the precision part with the needle, but how difficult would it be to push the needle through without a second hand to steady the frame, and how hard would it be to thread the needle? My grandpa could make her a sturdy frame that doesn't move if that's the only problem, but it would be best if she could thread the needle herself. She lives with other people who could help her, but she'll enjoy it more if she can do it self-sufficiently.

Thanks for any insight you can offer!
