My feet are too long!

I ran into this problem a while ago - I needed a short shank zig-zag foot and all I had were straight stitch ones.
Short shank feet are more expensive because they're popular. long shank feet are not because hardly anyone uses them any more.
So I bought a long shank zig-zag foot, making sure it covered the same area as the short foot.
I then took a tiny nail and tapped out the pins holding each foot in place and swapped them.
