Do you have more then one sewing machine? There’s nothing worse than arriving to class with the wrong foot pedal! Or even worse without your foot pedal! Linda, my tablemate from Sew Virginia Beach, suggested labels. Her machines have different pedals, so she labeled them prominently.
My machines have the same pedal, but I bought an extra to take to class. I keep it in my sewing machine’s case, so I don’t need to remember to pack it. I do the same with the power cord. If you have a spare already packed, you don’t need to remember it!
