Find a friend who knits.
My friend Lucy knitted me these fingerless gloves, and they keep me writing through the chilly conditions of my basement office in winter.
She also knitted me these slippers. (Yeah, I’m pretty blessed.)
After I’ve put some green tea on the kettle, wrapped my legs in a fuzzy blanket, and switched on my space heater, I’m good to go for another few hours.
Writing is sometimes a winter sport, after all.
