My home ec class was late 60's we had one semester of sewing from buying fabric, reading a pattern, laying out the pattern, cutting, and complete instructions on how the machine worked. We had to deep clean the machines, oil, and set tensions that the teacher had set to zero. We learned thread weight. How to sew straight, set in sleeves, interfacings, using bias tape, hem tape, darts, sewing elastic, pintuck, inserting lace, double needle and probably lots more. An hour a day for nine school weeks we learned a lot. After sewing we went to needlework, crochet, and knitting. The second year we did baking/cooking, personal care, and home interior, housecleaning and household budgeting. I learned so much in home ec.
