As a child I sewed on one of these!! My friend had one....we made little dresses for our dolls!! We had it clamped to a table!! I was around 8 yrs old at the time, and quite an 'accomplished' sewer!!! My Grandma taught me on a Singer treadle machine that my father had converted to an electric machine, when I was 6yrs old!! We spent many happy hours 'creating' outfits!!! Lovely memories!!
