I think the contestant was only punching holes in her paper pattern not the fabric, and then I agree with Ploshkin you then put tailors tacks in through the punched hole on the pattern piece which is still pinned to the fabric like we were taught at school. Now I am intrigued as to what this lady was using to cut the holes as I too am making my own patterns and could do with something like this – please does anyone have any ideas as to what this tool would be called?
Back in the 50's Vogue patterns were not printed, they were just plain tissue pattern paper and all the markings were shown by punched out symbols, so very easy to sew tailors tacks through the various symbol's holes.
In answer to Ploshkin’s question about marking balance marks etc. again I use tailors tacks – they really do not take that long and are easily removed even if they get caught up in the machine sewing – especially when sewing the darts, and this is where a pair of small surgical forceps are an essential part of our sewing kit – they remove even the most stubborn piece of thread that is caught in the stitching.
