I love the start/stop button and wonder how I ever used the foot pedal. Mine kept running away from me and I was forever chasing it down. I tried all the hints to keep it in place but they never worked. I don't use the thread cutter asI like longer tails to hold onto to start my seams. I don't use the knee lifter as it seems so cumbersome to have it there. I tried not getting it, but it came with themachines I have so they are somewhere around here but I don't know where.
