Hmm sewing the 'right' way and the 'wrong' way. I took a few general dressmaking classes about three years ago after I'd already been fumbling around for a good year, with the intention of learning how to do things the 'right' way. Well it was a waste of time for me, we went through the most basic tasks which I already knew how to do - self-taught and plenty of common sense
The lady teaching us was demo-ing something one day and although she showed us the correct procedure in theory, I do remember she got in a bit of a tizz and had to fudge around fitting it in place; hence I realised it's all part of the fun
I no longer feel a failure when I have to bodge something
