1980s middle school - various embroidery stitches, then a needle book with embroidered initials (whipped backstitch, I think, or possibly whipped chain stitch.) Pin cushion.
1980s secondary - how to thread up a sewing machine and fill a bobbin (already knew this from home). Different sewing machine stitches - making sure you followed a straight line! Different types of seam. How to set a zip. How to do button holes. How to add hook & eye. (Different types of fastener - I think we may have also done poppers.) Hemming.
Made a lined pencil skirt- I think you had to do a covered button in the same fabric, too, as well as set the zip.
I can't remember if I learned to make bias binding at school or home. Probably school - I think Mum just bought it.
We did use the sewing machine at home, so I could do quite a bit, but school was usually more precise - I don't remember Mum being too bothered about finishing seams. But it did mean I already had a good idea about how to read a pattern, if you needed to follow the nap, how to use interfacing and so on.
