I hate shoes so I am nearly always barefoot on the house Winter and summer. For some reason the only time I feel like my feet are cold is when I get in bed. I don't sew with shoes on either because I feel like I can't control the foot pedal as well. My friend laughs at me when we take classes since I have my shoes off there too. I do leave my socks on at classes but not at home. The only problem I see with barefoot sewing is the occasional pin or needle that I find on the floor the hard way.
