LOL Funny you should ask. Yesterday here in Missouri it was in the mid 70's. I found about six reasons to walk to my car last night, BAREFOOT! I came in and told my husband "its going to be a great spring and summer" I NEVER wear shoes unless there is ice/snow on the ground. If I have to leave the house to go in public I slip a pair of Adidas sandles on.
LOL To answer your question, NO I don't have anything on my feet when I sew.
