Oh, i have something similar to a previous poster.
My old machine has that thingy that moves up and down at the front of the machine with the thread - I don't know what it's called. take up lever?
Anyway, when it goes up, it sticks out past the top and front of the machine, and more than once I've been sewing really intense and gotten too close, and smacked my forehead with the lever. NOT PLEASANT!!! It's kind of hard to explain the bruising. Plus, the machine doesn't stop sewing as soon as you release the pedal, so I wound up with a few bruises right next to eachother. :roll: :oops:
