For me it varies according to the time of year. In the summer, it is in the afternoon when it is usually too warm to do much outside. I guess that is why I have not done much sewing this summer...it has been way cooler here in IN than normal. During the school year, I sew in the early evening. I have to be careful because I tend to say to myself that I'll just sew a little longer and the next thing I know, I'm up way too late. As a kdg teacher, I have to be on top of things all day long, so I really try to get to bed at a decent time.
