I've lost a lot of sensation in my feet and legs, makes things like walking a challenge, also kind of hard to know what I'm stepping on. So, I'm sewing tonite, put my foot back on the foo tpedal to resume stitching, my machine won't go, tap it a few more times, still no go. Getting very annoyed by this time (doesn't take long--my sewing room is hot). Tapped a little more aggressively.........the dog finally got up and moved.
