The edge stitcher foot is shown sewing two pieces of lace together and also making a French seam and pin tucks!
The gathering food is shown making shirring but also making puffing strips. The directions also suggest using a coloured thread in the bobbin so that the shirring resembles 'smocking' when used on a collar or cuffs.
The really complicated looking ruffler attachment can be used to make gathers on a single piece of fabric or ruffle and stitch the piece to a garment in one operation. The ruffler can also be set to make pleats in even sizes.
Now I know that many of todays machines also have these feet and capabilities, but it was interesting to see that a simple straight stitch sewing machine that is over 70 years old could also do these heirloom sewing techniques. And the fact that it is heirloom techniques that are featured in the manual for the machine.
