I can put my hand up to having learned on a treadle machine. My Mum had one it was her 21st birthday present, well she was 93 when she died and thats some 4 years ago. I remember standing by the machine watching her sew my clothes and especially remember her doing one of those swimming costumes for me that was elasticated and went into little squares. Probably had a go on the machine when I was around 12, but I was always sewing something or another by hand before then. Fond memories
