My computer room is cold. My house is an old house. We have lots of insulation in the ceiling but the outer walls are plastered brick.
We have good windows and have put plastic on the inside to help but my hand are always cold in the room. I saw kniting paterns for fingerless gloves but did not have the time to knit. I bought some small pieces of flece from Hobby Lobby and hand sewn some for me and it worked fine.
I just cut pieces that would go around my hand and sewed it up leaving room for my thumb. Warm as toast…now just waiting for spring.
