Now you've got me thinking of muff warmers (which always, ALWAYS sounds dirty to me, no matter how Victorian the context) and foot heaters in carriages, etc., and all the ways we humans have used over time to try to keep from shivering. I hope your shoulder pain eases post haste and that you keep yourself warm and cozy as you can!

Also, 310 words is a rockin' word count! No number shaming around here. No words are bad words when you're drafting. :-)
