Better for me in the summer, actually. It's cool in my house all summer. We have ceiling fans + have the A/C set @80 and the house stays cool in this hot, humid climate. Sometimes in the winter, though, there are areas of this house that don't get warm enough and my hands get too cold, stiff, and sore to do any sewing. We can pretty much keep the furnace turned off in the winter and keep the wood burning stove going, but not much of that heat reaches my usual sewing areas.
