Ah dont let that one go!
If and when she makes them for you, id be curious to see what they look like, if you wouldnt mind posting a pic here.
A custom pair for me would be seamless, and include stitched thumb holes
Wool knit arm warmers are a great layering insulater for the arms, are very adjustable and can just be pulled slightly to warm hands, or fully off from under your shell if youre overheating.

I wish i could retrace it but i lost it on a ride in manhattan, i tied it around the seatpost for some reason, and it mustve worked loose.
