My sewing room is at the end of the house furthest from our heat source so I have one of those little oil filled radiator looking heaters in there. I keep it set on the lowest setting so it only comes on when needed. I feel it is safer than a space heater because there are no exposed heating coils. It takes a while to get the room warm when it is first used but after it gets the room warm, it keeps it nice and comfy!
