It's so frustrating when you decide you want to sew something only to find halfway through a pattern you're asked to sew a box corner or a French pleat, or a bust dart and you don't know how to do it. Or how about the thing you really want to make but are put off because you don't know how to do an invisible zip? Fret no more. I've got together - all in one handy place - a whole load of basic "how to" sewing techniques. Sew, get to it!
