YIKES!
I have forgotten so much while I travel! One time my husband forgot to pack underpants when we went to China for a month. We went to a Chinese department store and tried to use sign language. We weren't doing too well when a Chinese man, who spoke perfect English, came up to us, saw our problem, and helped us out.........just too funny. We now have a list to pack with, but we still forget stuff!'
Hope you get your machine foot and can have some fun sewing!
