Pp mentioned cutting hair. Over 40 years ago I lived in Libya and hairdressers were few and far between. I had always been one for taking the scissors to my own hair as cutting my little boy's hair. It wasn't long before I was tackling the hair of several ex pats friends. Wouldn't have won any awards but it got us through.
Also sewing, at about 18 years old, many's the Saturday morning saw me cutting out fabric on the floor and wearing the dress dancing that night. One pattern and different fabrics, I had about 5 of the same empire line and sleeveless. Not a lot of fabric required as they ended about 4" above the knees.
