I had a sewing machine that sat in its own cabinet - the cabinet is a vintage Hollywood-style Pfaff cabinet, and I love it and don't want to part with it.
The problem is that I've seriously upgraded my old Singer to a Janome Horizon that won't fit in the hole, and my friend isn't around anymore to fix the hole to fit the new machine. So currently I've put a board over the top of the cabinet, and have the machine (which has its own extension table) sitting on top.
Great, except my working space has now been elevated by about 5", so I need a new chair. However, if I get a drafting chair to accommodate the height difference, I will have to figure out how to accommodate the foot pedal since my feet will be lifted off the floor.
