If I'm in the house I'm barefoot. In winter I may wear socks.
For all the ladies who mentioned having their right shoe off, and those who didn't, if you are right handed try sewing with your left foot (right foot if you're a left hander). I was told this in a class years ago. There was also a chiro/physio (not sure which) on Simply Quilts who recommended it. It felt strange at first but after all these years it's natural and my back doesn't suffer as much.
