"Almost all, if not all of them, have done at least one class on it before but they're all firmly convinced that it's too hard for them to do."

I've not done a class in it (nor done ay foundation paper piecing at all), so I may be missing some of the subtleties of the technique, but it doesn't seem at all complicated to me.

Place big enough scrap, sew line drwawn/printed on paper, fold back, press, trim, place next scrap, sew.... repeat until design/block/section is done, tear away paper along stitch lines... done - Right?
