I suppose it's some sort of withdrawal symptom after finishing a big project, I sometimes get a sense of emptiness after completing something big...
A different project always helps. Hand warmers are great idea, I personally use them all the time in winter.
I’m glad to hear that it’s not uncommon to feel this way. Thanks and I will get started on something today. I swatched for the socks yesterday, but that doesn’t mean I’ve abandonned the idea of arm warmers.
