[NFB-Blind-Crafters] looking for wrist warmers

[Lovette Yewchan]

Hi everyone,
I am wondering if anyone has knitted wrist warmers that are suitable for someone typing at the computer that really work?
I have a friend who does a lot of work at the computer and she is blind and her hands are always cold.
I’d like to make her something, but I want something someone has actually found useful.
Thanks.
Lovette
