MIL is a keen needlewoman, but her right index finger is badly distorted by arthritis. She's looking for a crochet hook with an ergonomic handle that might be easier to grip, but does not have the option to browse and try in wool shops.
Any recommendations? She's willing to buy a few different types to try, but is overwhelmed by the variety.
MIL holds the hook from underneath (a bit like a pen?).
